Summary The purpose of this research is to investigate the occurrence of two heavy metals (namely cadmium (Cd) and lead (Pb)) in the liver of hogs bred in different locations in Vojvodina. A total of 30 liver samples were collected from ten pig farms in Vojvodina for experimental purposes in the period from December 2017 to January 2018. The samples collected were analysed for the presence of lead and cadmium. The average concentration of lead in all the samples was 0.39 mg/kg wet weight, whereas the samples from only one farm of the ten considered were found to contain a slightly higher average lead concentration than permitted by the Serbian standard. A lead concentration of 0.86 mg/kg wet weight was detected in one liver sample from this farm. The maximum permitted lead concentration was exceeded in the liver samples obtained from three farms. However, all the liver samples analysed were found to contain the permitted levels of cadmium, with an average cadmium concentration of 0.12 mg/kg wet weight and a maximum cadmium concentration of 0.48 mg/kg wet weight. The occurrence of heavy metals and their origin in the pig’s offals should be examined in greater detail in future research, especially because pig’s offals are used in the meat processing industry.

SUMMARYCadmium and lead concentrations were compared in tissues of cutlassfish, Trichiurus lepturus L., its intestinal nematode Hysterothylacium sp. type MB larvae, and in water from the same location in the Sea of Oman. Metal accumulation in hosts, parasites and sea water was measured by ICP-OES. Hysterothylacium larvae from the intestinal lumen and visceral cavity showed much higher metal concentrations than in host tissues or sea water. Statistical analyses revealed no significant differences in metal accumulation between infected and uninfected hosts. Cadmium concentration in the host muscle was lower than in intestine, liver and gonad tissues. The mean concentrations of lead and cadmium in nematodes were 289·03 and 81·5 times higher than in host intestine, 188·4 and 225 times higher than in host muscle, 108·6 and 65·3 times higher than in host gonads, 70·5 and 19·5 times higher than in host liver and 3351 and 148 times higher than in sea water. The results show the value of this and possibly related nematodes as bioindicators of heavy metals and their potential use in environmental studies.

Cadmium And Lead

Every year, pollution by eco-toxicants of natural and anthropogenic origin is becoming more and more acute. Some of the most toxic among them are heavy metals, especially cadmium and lead. These elements do not decompose. Once released into the environment, these elements continue to circulate in water, soil, and air for a very long time, accumulating in plants and livestock products. Therefore, there is a problem of obtaining safe agricultural products in areas contaminated with heavy metals. In animal husbandry, synthetic and natural enterosorbents are used for obtaining safe products. For example, such enterosorbents are shungites, bentonites, diatomites, clays. We tested diatomite from the Kamyshlovskoye deposit at a dose of 5.0 g/kg of feed to reduce cadmium accumulation and lead during their combined intake. We investigated the feed intake of a combination of cadmium and lead at doses of 5.0 and 50.0 mg/kg feed. The result of this experiment is the accumulation of metals in the liver, kidneys, and bones, and, in addition, in the testes. The use of diatomite to reduce the accumulation of heavy metals has not been successful. There is an increase in lead accumulation in the liver, kidneys, and testes. The content of cadmium in diatomite is 3.86 ± 0.20 mg/kg, lead – 105.0 ± 7.2 mg/kg. The results obtained indicate that diatomite as a feed additive to reduce lead and cadmium intoxication did not show protective properties.

Water is a vital requirement for life and it is also an effective vehicle for the transmission of diseases if contaminated. Pollution caused by heavy metals is one of the major environmental problems that are imperative to be solved. Mining of solid minerals has been identified as an entry point of heavy metals into the environment consequently polluting various components of the environment such as soil and water. Bioremediation offers a promising means to reclaim such contaminated environment in an economical and eco friendly way. The focus of this study is to evaluate the bio sorption efficiency of cadmium and lead-resistant yeast from well water samples collected from Angwan Magiro, one of the lead-contaminated villages of Niger State, North Central Nigeria. Microbial enumeration of the water samples were carried out using pours plate technique, while physicochemical parameters were done by standard methods. Tolerance ability of the yeast isolates to the heavy metals was determined by cultivating on yeast broth supplemented with synthetic solutions of 1.50 mg/L cadmium concentration and 5.50 mg/L lead concentration. Based on the result of heavy metal tolerance assay, Saccharomyces cerevisiae was then selected to determine its efficiency in bio sorption of cadmium and lead in a rotary shaker incubated at an ambient temperature for a period of 28 days. Yeast cells were separated from solutions by centrifugation and the supernatants were analyzed for residual metals in solution using Atomic Absorption Spectrophotometer (AAS). Bio sorption experiment was carried out as function of solution pH. The results of this investigation reveal that Saccharomyces cerevisiae was efficient in the removal of lead with 99.54% and cadmium with 88.24% at pH 8.20. These findings suggest that Saccharomyces cerevisiae present in heavy metalcontaminated water could be an effective measure for remediation of the ecosystem.

We measured changes in atmospheric and blood levels of lead and cadmium in the South Korean general population during the past decade. Blood data of 16,873 adults were taken from the Korean National Health and Nutrition Examination Survey (KNHANES, 2008–2017). Atmospheric data were taken from 66 air quality monitoring sites in 16 different regions in South Korea. From 2008 to 2017, the geometric mean (GM) blood lead level decreased from 2.37 to 1.46 μg/dL (38.4% decrease), and the atmospheric lead concentration decreased by 61.0% in the overall population. During this time, the GM blood cadmium level decreased from 0.88 to 0.72 μg/L (18.2% decrease), and the atmospheric cadmium concentration decreased by 63.6%. Multiple linear regression analysis indicated that a half reduction in air lead was associated with a 0.09 μg/dL decrease in blood lead (95% CI: 0.03 to 0.15) in a subgroup of the metropolitan city population. However, a half reduction in air cadmium had no significant effect on blood cadmium. Multiple linear regression analyses indicated that the decrease in blood lead level over 10 years in Korea was related to the decrease in atmospheric lead concentration. However, the decrease in blood cadmium level during this time was not significantly associated with the decrease in atmospheric cadmium concentration. Our findings suggest that inhalation is a major source of lead exposure, but not of cadmium exposure. Ingestion of dietary cadmium presumably has a stronger impact on blood cadmium levels.

Samples of rock deposit dug out from wells at Alimosho local government in Lagos state, Nigeria were characterized for chemical composition and ultimate utilization. Fourier Transform Infrared Spectroscopy (FTIR), X-Ray diffraction (XRD) and Atomic Absorption Spectroscopy (AAS) were used to identify the rock as a mixed clay rock containing 35.04% Illite, 25.64% Illite plus Quartz, 22.20% Kaolinite and 17.09% Feldspar. This was corroborated by cation determination that showed the rock to be predominantly clayey rock. The mean concentrations of lead and copper in water of the wells in the rock location are 0.004mg/L and 0.05mg/L respectively while cadmium is less than detectable limit. The well water in the area studied is therefore not contaminated by these heavy metals. Heavy metals removal by the mixed clay from polluted underground water was studied using AAS. A general increase of sorption was observed with increase in the adsorbent dosage. 20g of the rock adsorbed a higher percentage of copper (80.23%) than lead and cadmium that were 70.25% and 65.83% respectively. The percentage of heavy metals adsorbed confirms the use of mixed clay minerals as a contaminants removal from the underground polluted water. The rock adsorbed copper readily than cadmium and lead. The maximum amount of lead removed from the contaminated underground water of the defunct battery site across the adsorbent dosage (5g, 10g, 15g and 20g) were 1.20mg/L, 3.19mg/L, 3.69mg/L and 4.09mg/L respectively indicating the effect of increase in adsorbent dosage in remediating the lead contaminated water. This data showed that the rock can be used to remove these heavy metals from contaminated water.

Research objective was to identify the specific features of distribution of microelements (zink, manganese, lead, cadmium) in organs and tissues of black-backed shad Alosa kessleri kessleri (Grimm, 1887) and Dolginsky herring Alosa braschnikowii braschnikowii (Borodin, 1904) caught in the Caspian Sea. Accumulated in the tissues and organs of fish in concentrations exceeding the maximum permissible limits, heavy metals pose a danger to human health. Sampling was carried out by the standard techniques, definition of minerals was made by method of atomic and absorbing spectroscopy using an atomic and absorbing spectrometer with electrothermal atomization of MGA-915 MD. The analysis of the obtained data showed that distribution of minerals in the organs and tissues of the studied herring species had a similar pattern: the highest concentrations of minerals were registered in the gills and liver, the smallest - in muscle tissue. In comparison with black-backed shad the organs and tissues of Dolginsky herring had higher concentrations of chemical elements. Zinc has been found to accumulate mainly in the liver; manganese, lead and cadmium - in the gills. Accumulation of zinc, cadmium and lead in the studied bodies and tissues of fishes exceeded acceptable level.

The present study was carried out to characterise the load of heavy metal in the forest soils of Dehradun during various seasons. Surface (0-15 cm) and sub surface (15-30 cm) soil samples were collected from four different sites during summer, monsoon and winter seasons. The results revealed that the maximum Cadmium concentration was recorded in surface (0-15cm) soils and minimum in sub-surface soils (15-30cm). The Cd concentration maximum during summer followed by winter and monsoon. Similar pattern of distribution of chromium was recorded in surface soil. The Chromium content was observed in the order of winter>summer>monsoon in surface soil and summer>winter>monsoon in sub-surface soils. The concentration of Copper in surface soils varied from 3.19 to 0.52mgkg-1 while in sub-surface soil, it varied between 2.25 and 0.57 mg kg-1. The copper concentration was maximum during winter followed by summer and monsoon. The lead concentration was recoeded maximum at site-II and minimum at site-IV whereas, it was recorded maximum during winter and minimum during monsoon. In general, all the heavy metals were found to decrease with soil depth. The concentrations of heavy metal were quite low but their presence in sites makes them potential to increase toxicity in future owing to more environmental degradation.

The concentrations of three toxic heavy metals, mercury (Hg), lead (Pb), and cadmium (Cd), were determined in preserved variegated scallops (Chlamys varia, Bivalvia, Mollusca), which are often consumed in Tenerife (Canary Islands, Spain). A total of 300 samples of seven commercial brands (A, B, D, H, J, L, and M) and one processed product (“scallop sauce”) were analyzed. Samples were collected weekly in a major shopping area in Santa Cruz de Tenerife during a 12-month period. The concentrations of lead and mercury were far below the maximum limit permitted for human consumption by the European Communities Commission regulation (EC) 466/2001 (1 and 0.5 mg kg−1 wet weight for Pb and Hg, respectively). Concentrations of cadmium were close to the maximum limit permitted by regulation (EC) 466/2001 (1 mg kg−1 wet weight).
