A comparative study of the lead and cadmium content of surface enamel of Belgian and Kenyan children

Information about the influence of zeolite used as adsorbent to reduce the concentration of Lead and Cadmium in separate links of trophic chain of hydroecosystem namelyn in water, phytoplankton and muscular tissue of Silver carp is given in the article. As a sorbent we used zeolite of Sokirnitsa deposit (village Sokirnitsa, Khust district Transcarpathian region) of fraction 1.0 – 4.0 mm. Investigations were made at the Lviv research station of Institute of fisheries NAAS (Lviv oblast, Horodok region, Velykyi Lyubin). The sorption properties of natural Transcarpathian clinoptilolite towards Lead and Cadmium at dynamic conditions have been studied. The paper represents research results aimed at estimating effectiveness of removing of Lead and Cadmium ions from hydroecosystems using natural mineral–zeolite. The dynamics of heavy metals content at phytoplankton and muscular tissue of silver carp (Hypophthalmichthys molitrix Valenciennes, 1844) was studied. Measurements were perfomed in pond № 24 (12) area 0.14 hectares which is fed by waters of the river Vereshchytsia. The pond depth is 1 – 1.5 meters. Results of investigations worked out statistically combining the groups. Considerable lowering of ions content of both metals in water was determined. The lowering of cadmium content in muscular tissue of Silver carp was much noticeable than the content of Lead. Results of such investigations are rather actual and perspective and will help to reduce the content of some toxicants in water medium. Improvement of water ecosystems after use of natural sorbents will guarantee ecologically safe products of fish culture and will increase the efficiency of the branch.

Bendungan Telaga Tunjung terletak di Desa Timpag, Kecamatan Kerambitan, Kabupaten Tabanan, Provinsi Bali. Dalam perkembangannya, wilayah sekitar bendungan dimanfaatkan untuk kegiatan pertanian, industri serta pemukiman yang memungkinkan terdapatnya masukan bahan pencemar seperti logam berat. Berdasarkan hal tersebut, perlu dilakukan penelitian mengenai kualitas perairan ditinjau dari kandungan logam berat, mengingat fungsi bendungan yang dimanfaatkan untuk masyarakat. Penelitian ini bertujuan untuk mengidentifikasi konsentrasi kandungan logam berat Timbal (Pb) dan Kadmium (Cd) pada kolom air dan ikan nila (Oreochromis niloticus, Linn.) di Bendungan Telaga Tunjung, yang dilakukan pada bulan Februari 2016. Metode yang digunakan adalah metode purposive sampling, dengan teknik pengambilan sampel air dilakukan secara komposit pada 5 stasiun berdasarkan perwakilan perairan bendungan. Pengambilan sampel air dilakukan sebanyak 3 kali setiap 2 minggu, dan pengambilan sampel ikan dilakukan secara acak sebanyak 1 ekor setiap 2 minggu. Kandungan logam berat dianalisis menggunakan alat Plasma Atomic Emission Spectrometer ICPE-9000. Kosentrasi logam berat Timbal (Pb) di badan air yang diperoleh berkisar 0 – 0,009 mg/l, dan Kadmium (Cd) berkisar 0,135 – 0,310 mg/l. Pada ikan nila, konsentrasi timbal tidak dapat terdeteksi, dan konsentrasi kadmium yang di dapat berkisar 0,330 – 0,728 mg/kg. Hasil tersebut menunjukkan bahwa perairan di Bendungan Telaga Tunjung telah tercemar oleh logam berat Kadmium (Cd), karena telah melebihi ambang baku yang ditetapkan Peraturan Gubernur Bali Nomor 8 Tahun 2007 tentang Baku Mutu Lingkungan Hidup dan Kriteria Baku Kerusakan Lingkungan Hidup Kelas II yaitu sebesar 0,03 mg/l, dan melebihi ambang baku yang ditetapkan SNI (Standar Nasional Indonesia) 7387:2009 sebesar 0,1 mg/kg untuk ikan dan hasil olahannya.

Abstract The aim of the study was to evaluate the contamination of animal muscle, liver, and milk with lead, cadmium, mercury, and arsenic. Determination of the elements was carried out using several techniques of atomic absorption spectrometry. Between 2008 and 2012, samples of muscles and liver from 1305 cattle, 2345 pigs, 758 horses (only muscles), 1721 poultry (chickens, turkeys, geese, ducks), and 736 samples of raw milk were collected. Only 48 (0.7%) samples exceeded the maximum acceptable levels of the elements, especially lead and cadmium. In the case of lead, the highest number of samples exceeding the legal limits was found in muscles of pigs (6), where the maximum value reached 0.376 mg/kg. For cadmium, the highest number of samples (22) with values exceeding legal limits was found in muscles of horses. The cadmium content in muscles of horses, at both the mean (0.052 mg/kg) and median (0.023 mg/kg), was in order of magnitude higher than that observed in cattle and pigs. Small percentage of samples with values exceeding the maximum levels of toxic elements in food of animal origin indicates a low risk for the consumers’ health.
