“…To make the problem even worse, the city is surrounded by mountains that entrap the polluted air. In addition to air pollution, several reports of high heavy metal content in soils (20), raw milk (21), and the hair (22) of people who live in this city point to lead exposure through food and water.…”

The aim of this comparative cross-sectional study was to assess neurocognitive impairment, haematological fi ndings, and clinical symptoms of lead exposure among 316 male battery plant workers aged between 20 and 61 years. Compared to 123 matched controls (matching in age and years of work), the exposed workers showed signifi cantly higher mean blood lead level (BLL) and lower haematocrit, haemoglobin, and red blood cell count. Mean BLL signifi cantly correlated with clinical symptoms such as nocturia, increased urination frequency, oedema, drop in deep tendon refl ex, concentration impairment, agitation, headache, depression, abdominal pain, palpitation, fatigue, and diminished sex drive. Workers with clinical disorders had higher BLL and lower haematological parameters. These fi ndings warn that silent toxicological problems caused by lead might go unnoticed by health professionals.

“…Seasonal variation in aflatoxin contamination may vary based on the feed type, processing and storage conditions. For example, demonstrated that the aflatoxin contamination was higher in winter (Tajkarimi, Aliabadi-Sh, et al, 2008;Tajkarimi, Faghih, et al, 2008). Higher rate for contamination during winter has also been indicated by SugitaKonishi et al (2008), in corn samples (Sugita-Konishi, Sugiyama, & Hiraokai, 2008).…”

“…All the milk samples stored at -20°C in clean polyethylene containers, and away from light exposure. Determination and elimination of lead and cadmium in milk samples: In this study, the furnace atomic absorption spectrometry as a sensitive method for measuring heavy metals (14,15) was used to determine the levels of lead and cadmium in samples.…”

A B S T R A C TBackground and Objectives: Heavy metals such as cadmium and lead are the most important toxins spreading through various ways like water, soil, and air in nature and easily enter human food chain. It is essential to determine the cumulative and harmful effects of these metals in nutrients, especially in cow milk because it is a unique source of food for all ages and it contains both essential and nonessential trace elements. Materials and Methods:A total of 100 milk samples were directly collected from healthy cows in Zabol located on east of Iran. The samples were tested to determine lead and cadmium residues. The rates of the heavy metals were determined using a Rayleigh atomic absorption spectrum equipped with hollow cathode lamps (HCL) at 283.3 nm for lead (Pb) and at 228.8 nm for cadmium (Cd). By using the photo-catalytic titanium dioxide nanoparticles, these toxic metals were removed. Results:The mean ± SD of the concentration of lead and cadmium in raw milk were 9.175± 2.5 and 4.557 ± 1.081 ppb, respectively. Also, the P-values of Kalmogorov-Smiranov test for lead and cadmium were respectively 0.057 ppb (P>0.05) and 0.435 ppb (P>0.05). TiO 2 nanoparticles were used to eliminate and remove lead and cadmium in milk samples. The results showed that there was a significant difference between lead and cadmium contents before and after adding TiO 2 nanoparticles (P<0.05). Conclusions:According to results of this study, there was a very low amount of toxic metals. So, it seems that it is not necessary to use TiO 2 in milk samples but these days it used frequently as an additive to some samples like milk to remove these pollutants.
