“…Where the chronic hazard index (HI) is the sum of more than one hazard quotient for multiple substances, CDI k is the daily intake of heavy metal (k) and RFD k is the chronic reference dose for the heavy metal k. HI values ˃ 1 shows that there is the chance that non-carcinogenic risk may occur and when HI ˂ 1 the reverse applies (Liu et al, 2013). Table 2.Shows the sample coding and data introduction of cosmetics products manufactured in Nigeria including manufacturing and expiry date, batch number and regulatory authorities (NAFDAC) number where available.…”

“…The results showed that for cosmetic products manufactured in Nigeria, only arsenic in Royal Gold Cortex ® with calculated non carcinogenic risk value of 1.56E-08 constituted a non-cancer risk while arsenic in St. Ives Body Cream ® (non-cancer risk value =4.68E-07), Bioclaire Body Lightening Lotion ® (non-cancer risk value =1.17E-06) and mercury in Crusader Medicated Soap ® (non-cancer risk value =5.47E-09) constituted non-cancer risks for cosmetic products manufactured outside Nigeria. Only arsenic is carcinogenic among the two elements examined (Liu et al, 2013), although the US EPA has determined mercuric chloride and methyl mercury as possible human carcinogen (Das et al, 2011 (1) and 10 -6 -10 -4 respectively set by USEPA (Liu et al, 2013;US EPA 2001). These imply that the chance of non-cancer and cancer risk resulting from exposure to these metals at these concentrations is unlikely; however, heavy metals are cumulative in nature due to their long half lives and therefore build up of these elements on continuous usage of these cosmetic products could be detrimental.…”

Forty two different cosmetic samples consisting of 16 facial cosmetics, 6 soaps, 1 shower gel, 12 emulsions, 2 underarm cosmetics, 3 nail cosmetics and 2 perfumes were purchased from department stores and cosmetic shops within Onitsha Main Market and Eke-Awka in Anambra, Nigeria. Seven of these cosmetic (16.67%) were locally manufactured in Nigeria while thirty five (83.33%) were imported into Nigeria. The cosmetics were ashed before digestion and filtration. The filtrates were assayed for mercury and arsenic with AAS SearchTech AA320N. Hydroquinone presence was identified by chromatographic test while steroids, nitrite and N-nitrosamines were identified by colour test and together were assayed by UV-spectrophotometer (Spectrulab 21). The health risk assessment methods developed by the United States Environmental Protection Agency (US EPA) were employed to explore the potential human health risk of Mercury and Arsenic in cosmeticsamples. Results showed that two (2) of the cosmetic samples contained mercury ( 0.003 + 0.000mg/kg and 0.07 + 0.00mg/kg) while three cosmetic samples contained arsenic (0.002 + 0.000, 0.002+0.000 and 0.005 +0.000 mg/kg). Hydroquinone concentration ranged from 1.14 + 0.00 -1.83 + 0.03 mg/kg (1.14E-02 -1.83E-02 %).Steroid was found in only two samples with concentration of 16.70 + 0.74 mg/kg and 17.63 + 0.74 while N-nitrosamines and nitrite occurred in nine and eleven samples in the range of 4.66 + 0.09 -43.52 + 0.47 and 0.87 + 0.02 -13.42 + 2.90 respectively. The total cancer and non-cancer risk results indicated that although the chances of cancer risk and non-cancer risk resulting from the use of these cosmetic products were unlikely, build up of these heavy metals overtime on continuous usage could be detrimental.

“…Significant positive correlations of Cr, Cd and Pb concentrations between vegetables and the corresponding soil were observed (R = 0.23** -0.26**, P < 0.01, n = 183), suggesting that the increase of metals in soil could influence their accumulation in vegetables (Figure 4). However, some other studies showed that heavy metals in vegetables had no significant relationship with soil metals (Liu et al, 2013). These different results may be caused by the difference of regional environment, soil properties, farming methods and pollution conditions.…”

A systematic survey of heavy metals and As concentrations in vegetables and soil in Chongqing was carried out to assess their potential health risks to local people. The results indicated that the Cr, Cd, Pb and As levels in some vegetables exceeded the Chinese safety standard of pollutants in food. The total carcinogenic risks of the heavy metals and As in 10 kinds of vegetables were all over the standard limits provided by USEPA and ICRP. Therefore, great attention should be paid to the issues of the heavy metals and As pollution in vegetables and the corresponding soil.

“…Use of phytoremediation alone can be time-consuming but it might be possible to enhance the remediation efficiency by intercropping with other remediation plant species (Llugany et al 2012;Ma et al 2012;Gupta et al 2013). Celery has been found to be a highly tolerant vegetable to some heavy metals such as Hg, Cd, Zn and Pb and its ability to remediate soil contaminated with both Cd and Zn has been observed and employed for several years in our laboratory Liu et al 2012;Liu et al 2013;Nai et al 2013).…”

Long-term application of sewage sludge resulted in soil cadmium (Cd) and zinc (Zn) contamination in a pot experiment conducted to phytoextract Cd/Zn repeatedly using Sedum plumbizincicola and Apium graceolens in monoculture or intercropping mode eight times. Shoot yields and soil physicochemical properties changed markedly with increasing number of remediation crops when the two plant species were intercropped compared with the unplanted control soil and the two monoculture treatments. Changes in soil microbial indices such as average well colour development, soil enzyme activity and soil microbial counts were also significantly affected by the growth of the remediation plants, especially intercropping with S. plumbizincicola and A. graveolens. The higher yields and amounts of Cd taken up indicated that intercropping of the hyperaccumulator and the vegetable species may be suitable for simultaneous agricultural production and soil remediation, with larger crop yields and higher phytoremediation efficiencies than under monoculture conditions.
