Latar Belakang. Timbal merupakan logam berat yang dapat memberikan efek buruk terhadap kesehatan manusia. Timbal masuk ke dalam tubuh manusia melalui saluran pernafasan, saluran cerna, dan kulit. Makanan dapat terkontaminasi oleh timbal apabila pengemasan tidak tepat, misalnya pada sala lauak yang dibungkus menggunakan kertas ketikan dapat masuk ke dalam tubuh. Objektif. Penelitian ini bertujuan untuk membuktikan adanya kandungan timbal pada sala lauak yang dijual di Pasar Raya akibat penggunaan kertas ketikan sebagai pembungkus. Metode. Penelitian ini bersifat deskriptif dan dilakukan di Laboratorium Air Fakultas Teknik Lingkungan Universitas Andalas pada Mei 2018 – November 2018. Jumlah sampel sebanyak 34 sampel terdiri 17 sampel sala lauak yang dibungkus kertas ketikan dan 17 sampel yang tidak dibungkus kertas ketikan dengan menggunakan teknik total sampling. Pemeriksaan sampel menggunakan alat ICP (Inductively Coupled Plasma). Hasil. Hasil penelitian didapatkan seluruh sala lauak yang dijual pedagang di Pasar Raya Padang positif mengandung timbal, baik yang dibungkus kertas ketikan maupun yang tidak dibungkus. Rata-rata kadar timbal pada sala lauak yang dibungkus sebesar 0,172 ppm dan sala lauak yang tidak dibungkus sebesar 0,167 ppm. Kesimpulan. seluruh sampel sala lauak mengandung logam timbal dan terdapat peningkatan kadar timbal akibat pembungkusan. Kata kunci: logam timbal, sala lauak, kertas ketikan   Background. Lead is a heavy metal that harms human health. Lead enters the human body through the respiratory tract, gastrointestinal tract, and skin. Food can be contaminated with this substance due to the improper type of packaging such as printed paper. Objective. This study aimed to prove the presence of lead in sala lauak sold at Padang Traditional Market due to the use of printed papers as wrappers.

In this study, the level of arsenic (As), lead (Pb) and cadmium (Cd) and also essential elements in beer samples consumed in Turkey were investigated using the inductively coupled plasma mass spectrometry (ICP-MS) method. The heavy metal-induced non-carcinogenic and carcinogenic risks were calculated. For essential elements, the calculated estimated daily intake of iron (Fe), copper (Cu), selenium (Se) and cobalt (Co) from beer consumption were compared with their toxicity reference values. Tukey post-hoc test showed that As was found at a significantly higher level when compared to Pb. Also, a significant correlation was found between As level and alcohol by volume percent. All samples had a hazard quotient and hazard index <1, indicating no non-carcinogenic risk from exposure to single or multiple heavy metals. Some samples exceeded the threshold limit of acceptable cancer risk for As in the high beer consumer group. This assessment showed that in addition to health implications based on the alcohol content of beer, there might be a carcinogenic risk associated with the heavy metals content of these beverages.

Heavy Metal Elements

At present, heavy metal elements in dust have great influence on air quality and human health,therefore, the content and influence of heavy metal elements on campus were studied. Firstly, PM10 and total dust in the autumn campus atmosphere were sampled for 10 consecutive days, and then digested by electric heating plate digestion method. Then, inductively coupled plasma emission spectrometer (ICP-OES) was used to detect and analyze the content and concentration ratio of seven heavy metal elements Cu, Pb, Cd, Zn, Cr, Hg and Ba in PM10 and total dust. Finally, through comparative analysis, it is concluded that heavy metal pollutants in the atmospheric environment are mainly Zn and Ba, and the concentrations of Cd, Zn and Ba are seriously exceeded, so the air quality in Xiqing District of Tianjin is poor, and the particle size distribution of Cd and Hg makes it easy to enter the human body, which is especially unfavorable to human health.

Abstract For the characterisation of the environmental mobility of heavy metal contamination in aquatic sediments, the EU Bureau of Reference has proposed a fractionation by sequential extraction procedure. For its validation, the CRM-701 sample is available containing Cd, Cr, Cu, Ni, Pb, and Zn. In this paper, the matrix-matched calibration problems are presented. A multi-elemental inductively coupled plasma-optical emission technique is employed for the detection of heavy metals in the extracts. It was established that the sensitivities are strongly influenced by the extractants, which causes significant matrix effects: the sensitivities are strongly influenced by the solvents applied in extraction steps; the summarised recoveries show an acceptable agreement with the certified values; however, in the individual extraction steps for certain elements significant differences may occur due to the neglected interferences. Therefore, further optimisation is required utilising the flexible line selection possibility offered by the HORIBA Jobin Yvon ACTIVA-M instrument.

Heavy metals are vital and necessary in our daily lives. Moreover, if the amounts of heavy metals are more than the acceptable amounts (mentioned by WHO) in soil, water, and air, indeed, they cause a lot of diseases in human bodies. Therefore, monitoring and measuring the amounts of heavy metals that are arduous and difficult are so important. In this review paper, a lot of studies that have been carried out on the determination and quantification of heavy metals in human bodies, soil, and water are considered. Moreover, the effect of toxicity of each heavy metal on human health is assessed. According to WHO, EPA, NIOSH, ACGIH, and clinical chemistry, the determination of heavy metals such as Cd, Pb, Zn, Hg, Cu, Mn is very important in the human body and Environmental matrixes.

In the era of industrialization, pollution has totally deteriorated the quality and diversity of life. Heavy metal contaminations are the major causes of environment deteriorations. The basic reasons are natural as well as anthropogenic. Chief sources of heavy metal contamination are air pollution, river sediments, sewage sludge, town waste composts, agricultural chemicals like fertilizers and pesticides, and industrial waste like factories releasing chemicals, anthropogenic activities, etc. Agricultural soils in many parts of the world are generally contaminated by heavy metal toxicity such as Cd, Cu, Zn, Ni, Co, Pb, Hg, As, etc. These are due to the long-term use of phosphate fertilizers, sewage sludge, dust from smelters, industrial waste, etc. Heavy metals in soils are detected with some specific instruments like atomic absorption spectroscopy, inductively coupled plasma, inductively coupled plasma-mass spectroscopy, and X-ray fluorescence and spectroscopy. Among all these instruments, atomic absorption spectroscopy (AAS) is the best because it gives the precise quantitative determination. AAS is a method applied for measuring the quantity of the trace elements present in the soil or any other samples.

Waste wood collected at the Vancouver landfill has been sorted based on the visibility of coatings, paints, and the green colorization of wood typically associated with wood preservatives. The sorted material was then ground and tested with an inductively coupled plasma mass spectrometry (ICP–MS) for heavy metal elements that are toxic or harmful to humans and (or) the environment. Results indicated that wood preservatives were not visually detectable but paints and coatings were. Therefore, the study demonstrated that visual sorting is not sufficiently accurate to distinguish between treated and clean or untreated waste wood.
