across the world. Digital education through the internet emerged as a possible solution
to classroom education, including in countries like India. A cross-sectional study was
carried out among higher secondary school teachers in Kerala, India. The main objectives
of the study were to assess the challenges faced in online education by educators of
higher secondary classes in the state. A total of 220 teachers were included in the study
by simple random sampling. A self-administered questionnaire was used to measure
impediments and challenges faced by the teachers. Among the study population, half
of them experienced a high level of impediments and challenges. In general, teachers
mostly faced challenges like lack of IT support, continuous technological changes, and
unequal internet access due to locality and geographical factors. Language teachers
experienced higher levels of impediments and challenges compared to other teachers.Not Availabl

The mechanistic pathways for mitigating As toxicity in rice and its risk to human health were assessed using a contaminated paddy-rice system with seven amendment regimes involving CaSiO3, FYM, and VC. The bioavailable and total As build-up of 1243 and 2550 g ha−1 respectively from control plots, while the amended plots had 672.8 and 502 g ha−1 reduction on average. The transfer of As from soil to grain was lesser in treated (4.3%) compared to control (6.5%). In treated plots, grain nutrient quality, such as Zn and Fe concentration, improved by 4.1–28.4% and 10.2–30.2%, respectively. The average incremental lifetime cancer risk of As associated with ingestion of such rice is 2.4 and 1.5 times lower on combined (0.47× 10−3–0.54× 10−3) and individual (0.74× 10−3–0.86× 10−3) application of amendments over control (1.13 × 10−3). To achieve the desired hazard quotient of < 1, the cleanup goals for total As in root, shoot, grain, and polished and cooked rice are 11.72, 3.99, 1.03, 0.28, 0.25, and 0.075 (mg kg−1), respectively. CaSiO3 with and without organic can reduce As concentration in the root, shoot, grain, polished rice, and cooked rice below the cleanup goals.Not Availabl
