Arsenic

Jun 29, 2021Arsenic. Arsenic is a naturally occurring element that is widely distributed in soils and minerals. Humans are regularly exposed to small amounts of arsenic in the air we breathe, the water we drink and the plants we eat. Arsenic is used as a pesticide primarily to preserve wood from rot and decay. In the past, arsenic was also used in rat

None of the treatment systems removed all of the arsenic from the drinking water. About one-half of the systems decreased the arsenic concentration to less than the maximum contamination level of 10 g/L. The effectiveness of the systems varied widely; the percentage of arsenic removed ranged from 2 to 90 percent, and the median was 65 percent.

Arsenic Toxicity in Soybean Plants: Impact on Chlorophyll

Aug 12, 2021Arsenic (As) is naturally present in soils and groundwater in agricultural areas, mainly in the form of arsenate (AsV) and arsenite (AsIII). It can enter soybean plants and decrease their yield and growth, therefore posing a serious problem. Our aim was to evaluate its effects on physiological events closely related to plant growth and the possible signaling pathways involved. Photosynthesis
