Levels of Cuprum (Cu) and Plumbum (Pb) in Shrimp in the Traditional Market and Their Impacts Towards the Environmental Health

Absorption of heavy metals by the main shrimp Cuprum (Cu) and Plumbum (Pb) will be accumulated in the body and cannot be biodegradable and accumulated in living tissue. Cuprum and plumbum in small amounts are needed in the body's metabolic process but exposure in excess amounts is toxic, so that at a certain level it can increase the risk of death. Heavy metal pollution often comes from human activities, namely industrial waste disposal, domestic waste or pesticide use in agricultural cultivation, plantations, as well as fisheries businesses, especially shrimp farming. This study aims to identify the magnitude of the average levels of cuprum (Cu) and plumbum (Pb) heavy metals in various types of shrimp available in traditional markets, by comparing the average levels of cuprum (Cu) and plumbum (Pb) of various types of shrimp, observation as well done by comparing the physical size of shrimp based on the type of shrimp. and determination of cuprum (Cu) and plumbum (Pb) levels was carried out by atomic absorption spectrometry. The results of research on shrimp sold in the traditional market of Surabaya, showed that the smaller the physical shrimp, the higher levels of cuprum (Cu) and plumbum (PB) will be higher. The highest Cuprum (Cu) and Plumbum (Pb) levels were found in Vannamei (Litopenaeus vannamei) shrimp, Cuprum (Cu) levels of 8,811 mgCu / kg, and Plumbum (Pb) of 1,990 mgPb / kg, on Windu shrimp (Panaeus monodon) Cuprum (Cu) levels of 7,886 mgCu / kg, and Plumbum (Pb) of 0.735 mgPb / kg, whereas for giant prawns (Macrobrachium rosenbergii de Mann) showed levels of Cuprum (Cu) of 5,814 mgCu / kg and Plumbum (Pb) of 0.728 mgPb / kg; this average level is higher than the WHO standard of 0.691 mgCu / kg for Cu, and 0.715 mgPb / kg for Pb
