“…Focardi and S. Aurigi, University of Siena, personal communication). A similar increase in the lipid level (and of some contaminants) was found while comparing the fish (Rutilus rutilus) collected in the river Seine upstream and downstream the polluting loads from Paris (Blanchard et al, 1997). However, it should be born in mind that such an increase of lipid reserve is not necessarily an indicator of fish health.…”

A comprehensive evaluation of the results of many recent and ongoing studies has been performed in an attempt to assess which stressors are acting and what alterations could be derived for the aquatic organisms of the river Po downstream from one of its tributaries, the river Lambro. With this aim in view, this stretch of the river Po was compared with the immediate upper reach which is characterized by an overall good quality. The comparison was based on four categories of indicators, that is, watershed stress, physical-habitat alteration, and in particular chemical exposure and biological responses both of which were thoroughly examined. The reach located downstream of the river Lambro was found to be contaminated by a complex mixture of pollutants that were detected at low/moderate concentration values. This makes the area representative of what can be considered as a 'grey' level of pollution, that is the most frequent condition of watercourses worldwide. Nevertheless, the effects derived from such moderate/low levels of contamination for aquatic life are difficult to assess. Most of the indicators were found to be changed downstream of the river Lambro and different kinds of alterations were observed in both resident species and laboratory-test organisms. Although more information is necessary to understand less evident impairments as, for example, of the fish community, it can be concluded that a continuous interaction between chronic toxicity and trophic enrichment is the process that characterizes this riverine environment and affects the community. On the grounds of these findings, some suggestions are also proposed pertaining to 'grey' areas and their investigation.

“…Picer and Picer (1995) studied levels and longterm trends of PCB and DDT in mussels in eastern Adriatic coastal waters and reported that mass fractions of chlorinated insecticides and PCB in mussels ranged from ND (<0.1) to 107.3 for DDT and from ND (<0.5) to 1,072 × 10 9 wet weight for PCB and from 19 to 35,600 for DDT and from 52 to 103,000 × 10 9 on an extracted organic matter basis. Blanchard et al (1997) studied the organochlorine distribution and mono-orthosubstituted PCB pattern in the roach (Rutilus rutilus) from the river Seine by high-resolution gas chromatography in spring and autumn and reported that in roach as well as in water samples of the Seine river, there is a fall of PCB contents in spring compared to autumn. PCB 153 and PCB 101 are major components in roach, while mono-orthosubstituted and less chlorinated compounds are in much lower concentration in roach.…”

In recent years, various environmental issues have aroused a concern on the pollution of pesticides in rivers and in their various intercompartments. Multiple residues of pesticides discharged from industries or as a result of extensive use of agrochemicals in agriculture have been monitored. These pesticide residues contaminate the river ecosystem and its intercompartments such as sediments, and aquatic biota, and make it harmful to humans when they contaminate food and drinking water. The pesticide contamination in water, sediments, and aquatic biota has been reported to be beyond the acceptable range. The most commonly found pesticides are organochlorine, namely, dichlorodiphenyltrichloroethane, hexachlorocyclohexane, endosulfan, heptachlor, lindane, dieldrin, aldrin, endrin, and others. The paper discusses the general description, classification, and toxicity of pesticides; it also aims to create public awareness among people and appraise them with various alternate methods to combat the problem of pesticide contamination. An attempt has also been made to elucidate the findings of various works on pesticides in aquatic system and to highlight the challenging aspects of pesticide contamination, which have not attracted the attention of investigators yet.

“…2) and had a mean value of 1.42 ± 1.02 ng l -1 (n = 22). These values are at least eight times lower than those found upstream and downstream of Paris in the 1990s (11.5 to 172.0 ng l -1 [see Blanchard et al 1997]). This decrease may be the result of tighter regulations of PCB use in Europe, especially in France.…”

The temporal dynamics of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were investigated in a heavily urbanized river (Seine River, Paris, France) from November 2009 to May 2010. Pollutant concentrations were in the range of 0.2 to 3.8 ng l(-1) (median 1.1) and 0.4 to 3.6 ng l(-1) (median 1.1) for ∑ tri-deca BDEs and ∑ 7PCBs, respectively. In addition, for both PBDEs and PCBs, the partitioning between the particulate and dissolved phases was investigated. Due to their low water solubility, PBDEs were mainly (>70%) bound to particles. In contrast, only 54% of ∑ 7PCBs occurred in the particulate phase, and their partitioning was influenced by the degree of chlorination. During the sampling period, PBDE/PCB fluxes were quite similar and ranged from 3 to 128 and from 6 to 125 g day(-1), respectively. The annual mass flow of PBDEs and PCBs was estimated to 10 kg for both. Contrary to PCBs and BDE-209, the temporal evolution of ∑ tri-hepta BDEs was related to particulate organic matter content, which is controlled by river flow variations. This suggests that they exhibit different sources or behavior in the Seine River.
