“…Besides, there is a study that showed the geometric mean for HLL of the ceramic plant workers (7.6 µg/g) was significantly higher than the persons who did not expose to lead (3.2 µg/g) (Strumylaite et al, 2004). Similar findings have been revealed in other studies (Bache, Lisk, Scarlett, & Carbone, 1991;Zaborowska, Wiercinski, & Maciejewska-Kozak, 1989). The direct exposed to lead of exposed group while working might also be the main reason of this finding.…”

Chronic exposure to low dose of lead can affect to every systems and organs of the human body. Lead poisoning have been found among communication radio-repair workers because lead is routinely used for soldering. The longitudinal study design was used to investigate blood lead level (BLL) and hair lead level (HLL), to determine the association of BLL and HLL with signs and symptoms of lead poisoning among workers and to determine the health risk assessment of lead exposure among workers. There were 66 repair workers in exposed group and 54 office workers in low exposed group at baseline. And, there were 54 workers in exposed group and there were 48 workers in low exposed group at endpoint. General characteristics, Knowledge, Awareness, and PPE used (KAP) of lead exposure, and signs and symptoms were investigated by using a questionnaire. Hair samples were collected to measure excreted lead level. Blood samples were collected to measure lead level and to diagnose anemia, hepatic and kidney functions. Hypertension was also assessed. Descriptive statistic was used to describe all variables. Chi-square test, Independent T-test, and MannWhitney U test were used to compare the variables between both groups. Spearman's correlation was used to determine the correlation between BLL and HLL. Binary logistic regression was used to determine the association of BLL and HLL with signs and symptoms. The results showed the average age, education levels, and study at Signal school of low exposed group were higher than exposed group except for milk drinking (P-value < 0.05). The low median scores of knowledge and PPE used among workers were shown. The highest median BLL and HLL of exposed group were 5.5 ?g/dL and 2.9 ?g/g, respectively. Low positive correlation between BLL and HLL was also found (P-value < 0.05). The associations between BLL and signs and symptoms including loss of appetite, nausea and vomiting, excessive tiredness or weakness, headache or dizziness, nervous irritability, muscle and joint pain, insomnia, and hypertension were shown (P-value < 0.05). And, there were the associations of nervous irritability and muscle and joint pain with HLL (P-value < 0.05). The adverse health effects for lead exposure can be occurred with a chance of 2.4 time in expose group at baseline and can be occurred with a chance of 2.5 and 3.5 times in low exposed and exposed groups, respectively at endpoint. The findings can be summarized that there were existing adverse effects of low lead levels on the workers. Because of low knowledge and used of PPE among workers, lead poisoning protection program that consists of increasing in KAP of lead exposure should be applied as a guideline.

“…Evidence accumulated since the late 80s suggests that hazardous airborne contaminants are emitted from the ring of ceramics. [26][27][28] Hirtle et al (1998) 29 have reported that signicant amounts of metals are present in the total suspended particulate matter emitted during the ring of ceramics. These measurements can explain the ndings of Hibbert et al (1999) 30 and later of Jones et al (2013) 31 who showed that signicant amounts of heavy metals are present in the blood of artisanal pottery workers.…”

Traditional pottery manufacturing involves firing of the ceramics in kilns, a process that leads to high concentrations of airborne particles that are harmful to human health. In order to assess the associated exposure levels and the involved risks, here, for the first time, we investigate the size, the concentration and the elemental composition of the particles emitted during the different stages of the ceramic firing process. Number size distributions of the emitted particles, having diameters in the range from 10 nm to 20 μm, were measured in a traditional small-sized pottery studio using a Scanning Mobility Particle Sizer (SMPS) and an Optical Particle Counter (OPC). The measurements showed dominance of the nanoparticle mode (i.e., particles smaller than 100 nm) when the kiln reached temperatures above 600 °C. The mean size of the particles ranged from 30 to 70 nm and their peak number concentration was 6.5 × 10(5) cm(-3) during the first stage of the firing process where the ceramics were unpainted and unglazed. During the second stage of the firing process, where the ceramics were painted and glazed, the mean particle size ranged from 15 to 40 nm and their number concentration peaked at 1.2 × 10(6) cm(-3). Elemental analysis of individual particles collected during the two firing stages and studied by Energy-Dispersive X-ray (EDX) spectroscopy showed that the emitted nanoparticles contain significant amounts of lead. These findings provide new information for understanding the health impacts of traditional pottery manufacturing, and underline the need for adopting adequate measures to control nanoparticle emissions at the source.
