    U svakodnevnom životu se susrećemo sa kemikalijama i kemijski opasnim tvarima, stoga uvijek postoji određeni rizik i opasnost po okoliš i zdravlje ljudi. U proizvodnji i industriji opasne tvari se redovito koriste, ali i zbrinjavaju. Potrebno je strogu pažnju obratiti pri označavanju, rukovanju i transportu takvih tvari. Također je vrlo bitno zakonski propisano ambalažiranje i skladištenje opasnih tvari na sigurna mjesta. Unatoč stalnom razvitku i korištenju mjera prevencije, kemijske nesreće se u određenim slučajevima događaju. Dakle cilj ovog završnog rada je približiti pojam kemikalija, kemijskog onečišćenja i kontaminacije, te analizirati kakvo djelovanje ostavljaju na zdravlje ljudi i biosfere u cjelini te na posljetku proučiti na koje načine i pokušaje se kontroliraju i zbrinjavaju kemikalije i opasne tvari.In our daily life, we encounter chemicals and chemically hazardous substances, therefore there is always a certain risk and danger to the environment and human health. In production and industry, hazardous substances are regularly used or disposed of. Strict care must be taken when labeling, handling, and transporting such substances. Legally prescribed packaging and storage of dangerous substances are also very important. Despite the constant development and use of prevention measures, chemical accidents do occur in certain cases. Therefore, the goal of this final paper is to bring closer the concept of chemicals, chemical pollution, and contamination, analyze the effect they have on human health and the biosphere as a whole, and finally, to study the ways and attempts to control and dispose of chemicals and dangerous substances

    Marihuana je drugi naziv za konoplju koji se u engleskom govornom području također naziva kanabis. Razlika između marihuane i konoplje što marihuana koja se koristi za biljku koji ima visoku razinu THC-a dok industrijska konoplja ima vrlo nisku razinu THC-a od 0.2%. Uzgajivač industrijske konoplje koji se odlučio za uzgoj pri čemu uzgajivač mora imati potrebnu dozvolu za proizvodnju ind. konoplje. Siguran transport ind.konoplje omogučuje se putem transportog osiguranja jer tokom transporta postoje mogući rizici nastajanja neželjenih događaja koji mogu prouzročiti oštećenje robe,prijevoznog sredstva i ozlijede vozača,. Kod svake razmjene robe potrebno je ugovarati osiguranja robe odnosno marihuane da bi roba bila isporučena kupcu onakva kakva je bila kada je prijevoznik preuzeo od prodavatelja. Preuzimanjem i prijevozom robe , prijevoznik će preuzeti odgovornost za robu sve do istovara odnosno dok ne isporuči kupcu.Marijuana is another name for hemp, which is also called cannabis in the English speaking world. The difference between marijuana and hemp is that marijuana used for a plant that has high levels of THC while industrial hemp has a very low THC level of 0.2%. An industrial hemp breeder who has decided to breed whereby the breeder must have the necessary permit for the production of indus. hemp. Safe transport of ind.hemp is provided through transport insurance because during transportation there are possible risks of unwanted events that can cause damage to goods, means of transport and injuries to the driver,. With each exchange of goods, it is necessary to arrange the insurance of goods or marijuana in order for the goods to be delivered to the buyer as the carrier has taken over from the seller.

    Interes za lovni turizam u Karlovačkoj županiji raste iz godine u godinu. Zbog specifičnog geografskog položaja te povoljnog položaja iz aspekta prometne povezanosti, Karlovačka županija ima mnogo potencijala za razvoj vrhunskog lovnog turizma. Bioraznolikost u Karlovačkoj županiji je velika, relativno niska gustoća naseljenosti u odnosu na druge županije tome još više doprinosi. Prirodne ljepote, prisutnost 4 rijeke, velike površine prekrivene šumom, područje na granici nizinske, brdovite i gorske Hrvatske, u svijetu su tek prepoznate kao turističko odredište. Takvo je "tlo" pogodno za razvoj i pokretanje lovnog turizma u Karlovačkoj županiji. U kombinaciji sa sve raširenijim ruralnim turizmom, "robinzonskim" kampovima i razvijenim riječnim turizmom, lovni turizam mogao bi postati vrlo privlačan domaćim, ali i stranim gostima. Ovaj završni rad ima za cilj definirati lovstvo kao gospodarsku djelatnost i lovni turizam, prikazati njegovu funkciju i realizaciju primijenjenu na Karlovačku županiju.Interest in hunting tourism in Karlovac County is growing from year to year. Due to its specific geographical position and favorable position in terms of transport connections, Karlovac County has much potential for the development of top hunting tourism. Biodiversity in Karlovac County is high, relatively low population density compared to other counties contributes even more. Natural beauties, the presence of 4 rivers, large areas covered with forest, the area on the border of lowland, hilly and mountainous Croatia, are just recognized in the world as a tourist destination. Such "soil" is suitable for the development and launch of hunting tourism in Karlovac County. Combined with the increasingly widespread rural tourism, "Robinson Crusoe" camps and developed river tourism, hunting tourism could become very attractive to domestic as well as foreign guests. This final paper aims to define hunting as an economic activity and hunting tourism, to present its function and implementation applied to Karlovac County

    Voda je najvažniji kemijski spoj bez kojega ne bi bilo života na Zemlji. Povećanjem broja stanovništva dolazi do onečišćenja okoliša, a time i vode. Svaka voda koja je jednom korištena u neku svrhu, postaje otpadna voda. Kako bi pročišćavanje otpadnih voda bilo što učinkovitije, potrebno je poznavati sustav otpadnih voda, izvore onečišćenja voda, utjecaj voda na ekosustav i metode pročišćavanja. Prvi dio rada opisuje pojam otpadnih voda, vrste otpadnih voda prema izvoru nastanka te njihove osnovne karakteristike. Drugi dio rada odnosi se na podjelu biljnih uređaja, opisuje parametre potrebne za rad uređaja te se navode prednosti i nedostatci biljnih uređaja. Glavni dio završnog rada daje uvid u pripremu, izgradnju i održavanje biljnih uređaja. Naglasak ovog rada je na nastajanju otpadnih voda te mogućnostima njihovog pročišćavanja pomoću biljnih uređaja.Water is the most important chemical compound without there would be no life on Earth. The increase in the number of the population leads to pollution of the environment, and thus of water. Any water that has once been used for some purpose becomes waste water.

    Održiv razvoj je složeni proces čiji je temeljni zadatak osiguranje ravnoteže u svijetu kroz ekonomske, društvene i okolišne pozitivne učinke te podrazumijeva promjenu dosadašnjeg načina života, stavova, vrijednosti, navika, ponašanja i djelovanja na svim razinama društva, od lokalne, regionalne, nacionalne do globalne razine. Od 1972. godine, od kada je dana prva definicija održivog razvoja, do danas organizirane su mnogobrojne Međunarodne konferencije, pod pokroviteljstvom Ujedinjenih naroda, doneseni su brojni programi, konvencije i dokumenti, a čiji je temeljni cilj održivi razvoj i ravnomjerni razvitak svijeta. Održivi razvoj je utemeljen na savjesnom iskorištavanju prirodnih resursa s ciljem održavanja prirodnih kapaciteta kako bismo u nasljeđe budućim generacijama ostavili prirodnih resursa u tolikoj mjeri da mogu nastaviti dostatan život na zemlji kao što živi sadašnja generacija. To je proces koji vodi brigu o uravnoteženom djelovanju ekonomskih, društvenih i okolišnih faktora s temeljnim ciljem brige o dobrobiti čovječanstva. Održivi razvoj danas predstavlja okvir za oblikovanje politika i strategija kontinuiranog gospodarskog i socijalnog napretka, bez štete za okoliš i prirodne izvore bitne za ljudske djelatnosti u budućnosti te se oslanja na ideju prema kojoj razvoj ne smije ugrožavati budućnost dolazećih naraštaja. Ekonomija ima centralnu ulogu u suvremenom svijetu i osnovne ideje koje se provlače cijelim područjem ekonomije su oskudnost resursa i želja za efikasnošću. Ekonomija predstavlja jednu od dimenzija održivog razvoja i uključuje odgovornu proizvodnju i potrošnju, ostvarivanje ekonomskog rasta i smanjenje nejednakosti, liberalizaciju trgovine, industrijskog rasta i inovacije i izgradnju globalnih partnerstva za održiv razvoj. Hrvatska je od samog početka bila aktivna sudionica procesa donošenja dokumenata važnih za globalan održiv razvoj i to u svim relevantnim tijelima Ujedinjenih naroda i Europske unije. Temelj za oblikovanje i provedbu svih javnih politika na nacionalnoj razini danas čini Nacionalna razvojna strategija Republike Hrvatske 2030, usvojena početkom 2021. godine, ključan strateški dokument Republike Hrvatske. U strategiji se društveno gospodarski rast i razvoj temelji na ciljevima održivog razvoja Programa za održivi razvoj 2030. Pozitivan primjer prihvaćanju koncepta održivog razvoja daje socijalna zadruga Humana Nova, društveno poduzeće koje djeluje na tri područja: okolišnom, društvenom i ekonomskom. Utjecaj koji Humana Nova ima na zajednicu nastaje djelovanjem kruga koji čine ljudi, planet i dobit. Humana Nova zapošljava osobe s invaliditetom i druge društveno isključene osobe za čije izazove današnje društvo nema kvalitetan odgovor. Na ovaj način4 Zadruga aktivno doprinosi održivom razvoju lokalne zajednice, povećanju zadovoljstva i kvalitete života marginaliziranih osoba i smanjenju siromaštva. Zadruga zbrinjava tekstilne viškove tako što ih reciklira ili stavlja u ponovnu uporabu te na taj način vodi brigu o okolišu, a dobit koju ostvaruju ulažu u očuvanje radnih mjesta i stvaranje novih, daljnji razvoj i širenje poslovanja, tj. u dobrobit zajednice. Zapošljavanjem marginaliziranih skupina, sakupljanjem tekstila, njegovom ponovnom uporabom i reciklažom te lokalnim suradnjama, aktivno doprinose smanjenju siromaštva, održivom razvoju lokalne zajednice te očuvanju prirode.Sustainable development is a complex process whose basic task is to ensure balance in the world through economic, social and environmental positive effects and involves changing the current way of life, attitudes, values, navigation, behavior and actions at all levels of society, from local, regional, national to global levels. Since 1972, when the first definition of sustainable development was given, numerous international conferences have been organized under the auspices of the United Nations, numerous programs, conventions and documents have been adopted, the basic goal of which is sustainable development and balanced development of the world. Sustainable development is based on the conscientious use of natural resources with the aim of maintaining natural capacities so that we can inherit other natural resources in future generations to such an extent that they can continue to live on Earth as the current generation lives. It is a process that takes care of the balanced action of economic, social and environmental factors with the fundamental goal of caring for the well-being of humanity. Sustainable development today is a framework for shaping policies and strategies for continuous economic and social progress, without harming the environment and natural resources essential to human activities in the future that will weaken the idea that development must not jeopardize the future of future generations. The economy plays a central role in the modern world. The basic ideas that permeate the entire field of economics are scarcity of resources and desire for efficiency. The economy is one of the dimensions of sustainable development and includes responsible production and consumption, achieving economic growth and reducing inequalities, trade liberalization, industrial growth and innovation, and building global partnerships for sustainable development. From the very beginning, Croatia has been an active participant in the process of adopting documents important for global sustainable development in all relevant bodies of the United Nations and the European Union. The basis for shaping and proving all public policies at the national level today is the National Development Strategy of the Republic of Croatia 2030, adopted at the beginning of 2021, a key strategic document of the Republic of Croatia. The strategy bases socio-economic growth and development on the goals of sustainable development Sustainable Development Program 2030. A positive example of accepting the concepts of sustainable development is given by the social cooperative Humana Nova, a social enterprise that operates in three areas: environmental, social and economic. The influence that Humana Nova has in common is6 created by the action of a circle made up of people, the planet and profit. Humana Nova employs people with disabilities and other socially excluded people for whose challenges today's society does not have a quality response. In this way, the Cooperative actively contributes to the sustainable development of the local community, increasing the satisfaction and quality of life of marginalized people and reducing poverty. The cooperative disposes of textile surpluses by recycling or reusing them, thus taking care of the environment and the profits they make are invested in preserving jobs and creating new ones, further development and expansion of business, ie for the benefit of the community. By employing marginalized groups, collecting textiles, reusing and recycling them, and local collaborations, they actively contribute to poverty reduction, sustainable development of the local community by nature conservation
