Can be seen from the loss of vegetation and organism associations [12] This in case of pollution in agricultural areas that are continuously deposited on agricultural land in the long run can reduce the productivity of crops and reduce the quality of agricultural products, and cause toxins in various agricultural and livestock products that bring negative impacts to humans who consume them [10]. Mercury froze at -38.9°C and boiled at 357°C [9]
