Heavy metal content in soil and consumption yield in the vicinity of petrochemical plant The research on soil and consumption yield quality at the impact zone of the petrochemical plant in Płock (ZRiP), conducted in the 1970s and 80s, proved that the emissions from the plant threatened the agricultural production within the area. As the emission levels from the ZRiP have significantly dropped in recent years, analyses were conducted in order to assess the current content of Cd, Cr, Cu, Ni, Pb and Zn in soils as well as in wheat grain and potato tuber cultivated within the area. The results showed that the soils were not contaminated with above mentioned heavy metals, but the level of cadmium was exceeded in potato tubers collected from three research points and in wheat grain collected from one point.

The environmental effects of mining and its impact on natural resources are of a holistic nature. One of the modern methods employed for the remediation of technogenically disturbed soils is the application of microorganisms. This paper studies the impact made by soil microorganisms on the accumulation rate of heavy metals in the substrate of waste rock dumps in the process of soil reclamation. Suspensions of soil microorganisms (microorganisms utilising mineral nitrogen forms / MUMN; microorganisms decomposing silicates / MDS; microscopic fungi / MF) were applied to the rock dump surface. Separate groups as well as their combinations were applied. The heavy metal content analysis did not indicate a significant exceedance of the maximum allowable concentration limits (MACL) in the soil of the waste rock. The only metal whose content exceeded the maximum admissible concentration limits was nickel. It has found that the application of microorganisms influences the concentration of several heavy metals due to pH level changes of the rock dump soil.

Рассматривается влияние пирогенного фактора на содержание тяжелых металлов (свинца, цинка, кадмия, никеля, меди, кобальта, хрома, марганца) и их внутрипрофильное распределение в буроземах под разной растительностью. Исследования проводились на мысе Островной и сопредельной территории япономорского побережья, прилегающей к пос. Заповедный Лазовского района Приморского края. Установлено, что в буроземах гари по сравнению с почвами сопредельных участков под дубовым лесом и разнотравно-кустарниковыми группировками наблюдается увеличение содержания рассматриваемых тяжелых металлов, что, вероятно, связано с их дополнительным поступлением с золой. Показано, что для буроземов гари характерны более высокие коэффициенты концентрации (Кс) свинца, цинка, кадмия, меди и марганца по сравнению с буроземами под лесом и разнотравно-кустарниковыми группировками. Отмечены различия в поведении элементов: свинец, кадмий, кобальт закрепляются преимущественно в аккумулятивно-гумусовых горизонтах, тогда как никель, цинк, медь, хром и марганец мигрируют вниз по профилю в иллювиально-гумусовые горизонты. Подсчет суммарного показателя загрязнения Саета показал, что в буроземах гари фиксируется допустимый (низкий) уровень загрязнения в поверхностном аккумулятивно-гумусовом горизонте и умеренно опасный – в иллювиальной части профиля. Однако применение поправочного коэффициента на токсичность элемента (Кт) при подсчете суммарного показателя загрязнения увеличивает Кс элементов, относящихся к 1 классу опасности – свинца, цинка и кадмия. Поэтому, несмотря на допустимый (низкий) и умеренно опасный уровни загрязнения, в данном случае следует обращать особое внимание на класс опасности загрязнителей. The research focuses on the impact of pyrogenic factor on heavy metal content (lead, zinc, cadmium, nickel, copper, cobalt, chromium and manganese) and its profile distribution in burozems under different types of vegetation in the Ostrovnoy Cape (the Sea of Japan) and the bordering territory, close to Zapovedny settlement of Lazovsky Disrict (Primorsky Krai). The results show that burozems of the burnt forest areas if compared to burozems of adjacent oak forests and grass-shrub communities demonstrate increased heavy metal levels, most likely due to heavy metal introduction with burnt down plant remains. Burozems of the burnt forest areas have higher concentration coefficients (Сс) of lead, zinc, cadmium, copper, and manganese than burozems of the forests and grass-shrub communities unexposed to fires. Of all the elements under study, lead, cadmium, and cobalt tend to accumulate most in accumulative-humus horizons while nickel, zinc, copper, chromium, and manganese migrate down the soil profile into humic-illuvial horizons.

Sungai Citarum merupakan salah satu sungai yang menunjang kehidupan sebagian besar masyarakat Jawa Barat. Akan tetapi, dampak kegiatan manusia telah membuat Sungai Citarum sebagai sungai yang tercemar. Penelitian ini dilakukan untuk mengetahui kondisi wilayah hulu Sungai Citarum dengan melakukan pengukuran multi parameter terhadap kondisi air di Sungai Citarum Hulu dan air sumur warga sekitar, terutama Sektor 7. Wilayah penelitian ini secara administratif berada di Desa Pangauban, Kecamatan Katapang, Kabupaten Bandung. Sampel yang diuji pada penelitian ini adalah sampel air sungai dan sampel air sumur milik warga yang tinggal di sekitar Sungai Citarum sebanyak masing-masing enam titik lokasi pengamatan. Hasil pengukuran parameter hidrologi dan kandungan logam berat pada sampel air sungai dan air sumur menunjukan bahwa nilai pH, suhu, dan TDS masih di bawah ambang batas tercemar, sedangkan nilai EC menunjukkan bahwa air sumur dan air sungai telah tercemar. Hal ini dibuktikan dengan analisa kandungan logam berat yang dapat dilihat bahwa terdapat kandungan logam besi (Fe) yang cukup tinggi di atas ambang batas air bersih sehingga air tersebut tidak dapat di konsumsi bagi warga, baik untuk air sungai maupun air sumur. Citarum River is one of the rivers that supports the lives of most of the people of West Java. However, the impact of human activities has made the Citarum River a polluted river in the world. This research was conducted to determine the condition of the upstream area of the Citarum River by conducting multi-parameter measurements to water conditions in the Upstream Citarum River Sector 7 and the wells of the surrounding residents. This research area is administratively located in Pangauban Village, Ketapang District, Bandung Regency.  The samples tested in this study were river water samples at six observation locations and well water samples belonging to the residents living around the Citarum River as many as six observation location points. The results of measurements of hydrological parameters and heavy metal content in river and well water samples indicate that the pH, temperature, and TDS values are still below the polluted threshold, while the EC values indicate that well water and river water have been polluted. This is evidenced by the analysis of heavy metal content which can be seen that there is a high metal content of iron (Fe) above the threshold of clean water so that the water cannot be consumed by residents, both for river water and well water.Kata kunci : hidrologi, logam berat, Sungai Citarum

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
