Human exposure at chemical risks owes both to environmental factors (air, water) and food (vegetables, meat, milk, honey, etc.). These factors act simultaneously and cumulatively, the effects of certain wastes and contaminants are very complex and difficult to assess. In this paper, the risk assessment of nitrates for the inhabitants from West side of Romania is reported. Nitrates are processed from animal food (meat and meat products, milk and milk products), vegetables (spinach, salad, potatoes) and drinking water coming from local water sources, which are uncontrolled and very much polluted with nitrogen compounds. The estimated daily dose (EDD) was calculated for two scenarios, both for adults and children. The risk of nitrates ingestion at adults expressed as HR (Hazard Ratio) was sub-unitary and therefore, negligible. The risk of nitrates ingestion at children as HR was over-unitary but very close to 1, and can be removed by using water from controlled water sources and a special diet, which consists of vegetables from “without risk” series from this point of view. |
