Behavioural Responses

Selected behavioural responses of marine fishes and invertebrates which are reportedly capable of disruption or impairment by petroleum, heavy metals, pesticides and other pollutants are listed. The usefulness of these and other performance functions to regulatory agencies charged with formulation of saline water quality criteria appears somewhat limited. At present, however, motor functions such as swimming performance, locomotion, and equilibrium, as well as physiological responses, especially respiratory patterns, may have some potential for biomonitoring of wastes discharged into coastal environments.

Industries, as a source of pollution, have a considerable impact on aquatic ecosystems due to the diversity in the composition of their wastewater. In this study, it is aimed to determine the heavy metal pollution caused by the wastewater of milk products factory, paint factory and textile factory in the Organized Industrial Zone of Kahramanmaraş province. For this purpose, seasonal concentrations of some heavy metals (Fe, Cu, Zn, Cr, Ni, Cd, As and Hg) have been determined in wastewaters of milk products factory, paint factory and textile factory and in the region where these wastewaters discharge in the Erkenez Stream. The seasonal variation of heavy metals in all stations, generally the lowest concentrations of all elements were determined in winter and the highest concentrations were determined in summer. When the heavy metal contents of milk products factory, paint factory and textile factory wastewaters were compared, the highest values were found in textile factory wastewater. When all stations are taken into consideration, according to USEPA and water quality criteria, it is determined that the wastewaters of milk products factory, paint factory and textile factory and the area of the Erkenez Stream, where these wastewaters are discharged, were very dirty in term of heavy metals. When these results are taken into consideration, it is clear that the wastewater of these factories causes serious heavy metal pollution in the Erkenez Stream.

Due to the extension of wastewater treatment plants to nutrient removal and the development towards reuse of sludge in agriculture, new guidelines for regulating industrial discharges in Denmark were needed. The paper describes how a concept for regulating the discharge of specific organic substances and heavy metals has been developed during the past two years. The concept is based on guidelines that are made according to considerations of the environment and the treatment plant system, and that encourage the introduction of a cleaner technology and integrated preventive measures. For most organic substances, present knowledge of fate and effects in biological treatment plants is too scarce to underpin the setting of general standards. Therefore, it has been decided to base the developed priority system on the data used in the EEC-system for classification of hazardous chemicals. This includes ready degradability, defined by the OECD-test, bio-sorption and bio-accumulation, defined by the octanol/water distribution coefficient and toxic effects on water organisms. Several potential effects of seven heavy metals have been evaluated, and the most critical effects were found to be the quality criteria for sludge intended for use in agriculture, and the quality criteria for the aquatic environment. Proposals for general guidelines have been calculated using a simple mass balance model combined with water quality criteria and the Danish limit values for use of sludge in agriculture.

Diffusive Fluxes

To clarify the mechanism controlling the migration of uranium and typical heavy metals at the sediment–water interface, four sampling cores were collected along the Mianyuan River near a phosphate mining region to investigate their distribution in pore water and sediment along vertical profiles. This study indicated that: (1) the average concentrations of U, Cd, Cu, Pb, Zn and Ni in the pore water were 2.17, 0.08, 6.28, 1.78, 80.56 and 5.18 µg l−1 , respectively, some of them being higher than the National Recommended Water Quality Criteria. (2) The enrichment of U, Cu, Pb, Zn and Ni in the sediment near the urban area clearly indicated that local industries were important pollution sources. (3) The average diffusive fluxes of U, Cd, Cu, Pb, Zn and Ni of the four profiles were 0.016, 0.007, 0.300, 0.022, 2.925 and −1.328 µg/(m2·d), indicating that most of the metals diffused from the sediment pore water to the overlying water. (4) The IWCTU (Interstitial Water Criteria Toxic Units) values of Pb in the pore water exceeded 1 in most river sections, indicating that the toxicity levels in the sediments presented a risk to aquatic organisms.

Sewage Discharges

Intermittent discharges of storm sewage from combined sewer overflows continue to be one of the principal causes of poor water quality in many urban rivers in the UK. Despite the persistent nature of this problem, very little attention has been given to the study of how discharges of varying magnitude, duration and frequency affect the ecological quality of receiving waters. This information is of critical importance for deriving meaningful water quality criteria for the control of intermittent pollution. This paper describes the results of a study which has been carried out on Pendle Water, a river which flows through the urban catchment of Burnley, Lancashire, UK. Both the chemical and biological quality of Pendle Water are adversely affected by storm sewage discharges during heavy rainfall events. The ecological investigation has been primarily concerned with impact of these episodic discharges on benthic invertebrate communities and physiological responses in fish. Quantitative sampling of macroinvertebrates has indicated that storm sewage discharges may have a significant impact on the structure and diversity of benthic communities in receiving waters. Physico-chemical properties of habitats appear to be altered in a way which tends to favour the proliferation of certain pollution-tolerant species and decrease the abundance of taxa intolerant of organic pollution. Insitu bioassays, including the WRc Mark III Fish Monitor, have been deployed to investigate physiological responses to storm events of different magnitude, duration and frequency. Results are discussed in relation to their application in the field validation of proposed water quality criteria for the control of intermittent pollution from combined sewer overflows.

Heavy Metal Pollutants

Water quality criteria are the scientific basis for formulating water quality standards and environmental management practices. Due to the development of urbanization and industrialization, the problem of heavy metal pollution has become a serious environmental problem. Heavy metals not only have major impacts on aquatic organisms, but also seriously threaten human health. However, the current environmental criteria refer to the maximum value limitations of environmental factors in environmental media where harmful or detrimental effects are not produced on specific protected objects. This study reviewed the sources, hazard levels, toxic effect mechanisms, and the current research status of China’s water quality criteria for heavy metal pollutants. In addition, the focus and direction of future research on the toxic effects of heavy metal on aquatic organisms and the necessary criteria changes were discussed. The present study would provide an important theoretical basis for the future research of water quality criteria and risk assessment of heavy metal pollutants.
