The diuron threats severely aquatic organisms, especially the sensitive species. This compound causes kidney disease, haemolytic anaemia, compensatory haematopoiesis, endocrine problems and it is also potentially cancerous. The diuron is highly stable and persistent, mainly in aquatic environments. Īmong pesticide, the diuron is a widely used pesticide for weeds control, very effective and a worldwide antifouling agent. At molecular level, the pesticides have a negative impact too on the nervous system, causing serious health issues, such as carcinogenicity and neurotoxicity, as well as the alteration of oxidative enzymes, leading to oxidative damage of tissues. This usually leads to increased mortality rates, decrease in biodiversity, including the meiobenthic communities in marine habitats. At community level, the pesticides impact negatively the animals by altering their behavior and physiological functions. These products are often persistent and their long-term undesirable effects are highly visible at community, individual and molecular levels. Following their use, the pesticides reach various compartments of the biosphere, where they interfere with different types of ecosystems, affecting their integrity and functionality. The pesticides are organic toxic pollutants because they induce severe unwanted effects on humans and environment. However, their misapplication has become a major problem, mainly in developing countries. Nowadays, the use of pesticides has gradually increased worldwide to meet the needs of the growing human population. They are used on a large scale, comprising under this generic name the insecticides, herbicides, fungicides and various other substances. Pesticides comprise natural or synthetic substances intended to deplete unwanted pests, considered undesirable for agriculture and public health. Marine ecosystems receive daily numerous chemicals as a result of anthropogenic activities, reducing their ecologic and economic value, as well as for humans themselves.
