Investigation of Toxicological Properties of Organic Agricultural Waste

Abstract

The increasing volumes of formation and accumulation of organic agricultural waste pose the task of investigating the nature of the impact of waste on the environment and finding ways to efficiently dispose of them. The toxicological properties of organic animal waste (cattle manure) were investigated by the method of biotesting. Planktonic non-oceanic crustaceans Daphnia magna Straus were used as test objects. The physicochemical characteristics of the waste were also determined: humidity, ash content, bulk density, the value of the hydrogen pH of the water extract. It is shown that the waste has hazard class IV, that is, it is low-hazard. Possible ways of waste disposal in the conditions of an agro-industrial enterprise are considered.
