This data article aimed to investigate the quality of drinking water of Qorveh and Dehgolan Counties in Kurdistan province based on the water quality index (WQI) and agricultural quality index based on RSC, PI, KR, MH, Na, SAR and SSP indices. Also, Piper diagram was used to determine hydro chemical features of the groundwater area. The calculation of WQI for groundwater samples indicated that 36% of the samples could be considered as excellent water and 64% of the samples were classified as good water category. The results of the calculated indices for agricultural water quality indicate that water quality in all collected samples are in a good and excellent category. The Piper classification showed that dominant type of groundwater hydro chemical faces of region was calcium bicarbonate (Ca-HCO3−).

The aim of this study was to evaluate the groundwater quality Indices of Groundwater resource for Agricultural Use in jolfa city (Iran) during one decade (2003–2013). Data showed in the first and end year of the study period, the Mean±SD of Sodium Adsorption Ratio (SAR) and Sodium Percentage (Na%) indices 5455.77±3878.02, 3638.69±3565.19 and 51.49±15.65, 41.58±17.69, respectively. The data indicate that the, in terms of sodium percentage and sodium adsorption ratio, the water quality in this area is not suitable for irrigation.

Background Parabens are widely used to prevent organism growth and increase the shelf life of foods, medicines and personal care products (PCPs). Recent studies indicate their potentially harmful effects on human health. There is no information on the extent of exposure to parabens among Iranians. Methods We measured the concentration of urinary methylparaben (MP), ethylparaben (EP), propylparaben (PP) and butylparaben (BP) among Iranian adults and calculated their estimated daily intake (EDI). Also, association between the level of urinary parabens with socio-demographic and lifestyle variables were investigated. Results Detection frequencies of MP, EP, PP, and BP were 98.9, 91, 94.3, and 88.2%, and their median urinary concentrations were 69.06, 9.10, 12.4, and 9.87 µg/l, respectively. Urinary parabens were higher in females, and the difference in the concentration of MP and PP was significant. A significantly positive correlation between MP and PP (r = 0.638) and a moderate to a weak correlation between other parabens were observed. There was a significantly negative weak correlation between age and MP, BP and PP. There was also a significant association between different age groups and MP, BP and PP as well as different BMI values and MP. The highest EDI value belonged to MP in the female group. Despite being lower than the acceptable daily intake (ADI), its value was higher than that reported in other countries (except the US). Conclusions Our findings indicated that Iranians are widely exposed to the parabens and the range of exposure was associated with socio-demographic factors. These results could serve as a basis for assessing the risk of exposure to parabens amongst Iranians.

Despite the widespread use of parabens as antimicrobial preservatives in personal care products (PCPs) and foodstuffs, recent studies show that exposure to parabens could result in endocrine disruption. The urinary methylparaben, ethylparaben, propylparaben, and butylparaben among 100 adolescents and their relationships with using 19 personal care and 18 food products were evaluated. Urinary paraben concentrations were significantly higher in the high-user group (8-19 products) compared to both low (0-3 products) and middle (4-7 products) user groups. The frequency of PCP use was associated with higher urinary levels of 4 parabens, and the frequency of food product use was associated with higher urinary methylparaben and ethylparaben. The use of mouthwash was associated with higher levels of methylparaben, ethylparaben, and propylparaben. Users of makeup base had higher methylparaben and propylparaben, users of eye makeup had higher propylparaben, and users of body wash, sunscreen, and lotion had higher urinary propylparaben than nonusers. Consumers of dairy products had significantly higher urinary methylparaben, propylparaben, and butylparaben, and cookie consumers had higher urinary methylparaben and ethylparaben, than nonusers. Consumers of canned foods and chips/snacks had higher methylparaben, and consumers of sauces and jams had higher ethylparaben than nonconsumers. The findings show that certain types of foods and personal care products could be important sources of paraben exposure.

Background: This study aimed to examine the associations between the urinary concentrations of phthalate metabolites among a sample of Iranian pregnant women with anthropometric measures of neonates.Methods: Urine samples were obtained from 121 pregnant women at their rst trimester of pregnancy; the levels of monobutyl phthalate (MBP), monobenzyl phthalate (MBzP), mono-2-ethylhexyl phthalate (MEHP), and mono (2-ethyl-5hydroxyhexyl) phthalate (MEHHP) metabolites were determined by gas chromatography mass spectrometry (GC/MS). The correlation between the urinary concentration of these metabolites and some sociodemographic factors of the participants (maternal education, age, family income, pre-pregnancy body mass index), their lifestyle variables (smoking habit, food pattern, and physical activity), cleaning products use data (cosmetic and household cleaning products) with anthropometric measures of neonates were investigated.Results: MBzP, MBP, MEHP, and MEHHP were detected in 100% of participants with the concentration ranged from 120 to 860 μg/g creatinine.Signi cant correlations were observed between the urinary levels of maternal MBzP (adjusted β =0.3 (0.001), p=0.03) and MEHHP and (adjusted β =0.3 (0.001), p=0.04) with the birth weight of female neonates. MBP (adjusted β = -0.3(0.02), p=0.04) and MBzP (adjusted β =-0.3 (0.001), p=0.02) were found negatively associated with head circumference in male and female newborns, respectively. Signi cant differences existed in the birth weight of infants whose mothers used plastic packaging for pickle and those who had history of passive smoking (p-value< 0.05).Conclusions: the studied metabolites had higher concentration in the Iranian pregnant women urine compared to the other countries. Higher levels of prenatal exposure to phthalate metabolites may adversely impact the health status of newborns.
