“…At point P2, methyl parathion was found in only 15% of the samples. Galindo-Reyes et al (1999) found concentrations higher than those observed in our study. Moreover, Ccanccapa et al (2016) identified this compound with a low frequency and concentration.…”

ABSTRACT:The knowledge of pesticide residual concentrations in the environment is important to understand the threats to the environment and human health, especially when natural resources are used for human consumption. In this context, this study aimed to assess the potential ecological risk and respective sources of sediment contamination by organochlorine and organophosphorus pesticides. The study site was an urban lake located in Cascavel city, western Paraná state, Brazil, where the history of land use and occupation in the urban environment is typically agricultural. Surface sediment samples were collected every three months from April 2010 to June 2013 at five different collection points, totaling 65 samples. Analyses showed that contamination by organochlorine pesticides is related to agricultural activities in the past, with a low ecological risk to benthic organisms. Conversely, organophosphorus pesticides presented a recent and continuous contamination from urban activities, with a risk coefficient, especially for disulfoton, indicating a significant potential adverse effect on organisms. However, in general, the obtained results did not indicate an immediate risk to public health.

“…) were also realistic since they were consistent with those found by Galindo-Reyes et al (1999) (Reddy & Rao 1986, Betancourt-Lozano 1999. It might also have resulted from organophosphorous inhibition of acethylcholinesterase activity (AChE) (Srinivasulu et al 1990, Hertel 1993, Lundebye et al 1997).…”

“…In addition, investigations into the distribution of some of these highly toxic compounds in the coastal areas of Central America and Mexico have revealed that they have the potential to negatively impact sensitive tropical marine ecosystems (Readman et al 1992). Pesticide measurements in Ohuira Bay on the coast of Sinaloa, Mexico also revealed the presence of restricted and illegal pesticides (aldrin, endrin, methyl parathion, DDT and lindane) in sufficiently high concentrations to cause physiological and biochemical damage to shrimp and other animals (Galindo-Reyes et al 1999). Thus, coastal pollution is a problem in Mexico and other areas of the world, and there is a legitimate concern about the direct and indirect effects on non-target organisms, including wild and cultured shrimp.…”

Effect of methyl parathion on the susceptibility of shrimp Litopenaeus vannamei to experimental vibriosis

Following increasing calls for environmental safety over the past 2 decades, persistent pesticides are being replaced by more rapidly degradable products. However, even these pesticides can affect non-target species, and may be associated with slow growth and increased susceptibility to viral and bacterial infections. In this study, juvenile white shrimp Litopenaeus vannamei (also named Penaeus vannamei) were challenged by intramuscular injection with Vibrio parahaemolyticus after 4 d prior exposure to methyl parathion in feed pellets at 0.080 µg g -1 . The bacterial injection control group consisted of shrimp fed pellets containing the methyl parathion-carrier solvent acetonitrile. Three additional control groups comprised 2 sterile saline-injection groups fed pellets containing methyl parathion or acetonitrile prior to injection, and 1 uninjected group fed normal pellets. Cumulative mortalities were recorded on the 4th and 8th days, and the presence of histological lesions was recorded on the 8th day. Cumulative mortalities were significantly higher in the group exposed to methyl parathion and bacteria on Day 8. Histological lesions, typical of vibriosis, were significantly associated with the injection of V. parahaemolyticus. The study provides strong experimental evidence that prior exposure to methyl parathion can increase the severity of Vibrio infections.
