Determination of lead and cadmium contents

The lowest level of Pb was found in products of Saudi Arabia 0. The mean differences of local and exported products were significant at the 0. In case of Cd, the recorded levels were in the ranges of 0. The levels of Ni in ibuprofen products were in the ranges of below detection limit to 0.

MATERIALS AND METHODS

Greece products showed comparatively higher levels than UAE products and the levels were nondetectable in products of Saudi Arabia. The products of Germany exhibited highest level of Pb 1.

Determination of lead and cadmium contents

The recorded levels of Cd were in the ranges of 0. In case of Ni, lowest level recorded in UAE products 0.

The maximum daily ingested mass of Pb was higher from products of Greece 1. The maximum daily ingested mass of Pb from acetylsalicylic acids products were 0. However, the maximum recommended daily dose for Germany's product was higher 3.

Determination of lead and cadmium contents

Five solid dosage forms paracetamol mg were studied under this class; two products were manufactured in UAE, two exported from Saudi Arabia and one from Australia Table 4. The recorded level of Pb in paracetamol tablets were in the ranges of 0. The highest level recorded in one of the products of Saudi Arabia and one of the UAE products exhibited lowest level of Pb.

The maximum daily ingested mass of Pb from paracetamol tablets were 1. In comparison, between local and exported products, the mean differences of UAE and Australia's products were significant at the 0.

The maximum daily ingested masses of Cd from these products were in the ranges of 0. Higher level of Pb, Cd and Ni were recorded in syrup than suspension and local product showed higher levels of Pb and Cd than exported one except Ni, where the product of Australia contained higher level of Ni than local products.

The products of UAE exhibited lower level of Pb 0. However, the recorded level of Ni was higher in UAE products 0. However, the mean differences of local and imported products were significantly different.

The maximum daily ingested masses of Pb from these products were in the ranges of 0. The recorded levels of Cd in these products were in the ranges of 0. The calculated maximum daily ingested masses of Ni from these products were in the ranges of 0.

In comparison between two products of UAE, diphenhydramine 7 mg contained higher level of Pb but lower level of Cd and Ni than diphenhydramine 13 mg.

The contents of lead, cadmium, chromium, copper, and nickel were determined in 25 tea samples from China, including green, yellow, white, oolong, black, Pu'er, and jasmine tea products, using high-resolution continuum source graphite furnace atomic absorption spectrometry. In Ghana, a complete profile of heavy metals in lipstick products is lacking. Therefore, this study aimed to assess the level of some toxic metals in lipstick sold at . The total arsenic, cadmium, and lead contents were lower than the established legislative values, except for total arsenic in one brown rice sample. This study indicated the need to establish monitoring programs for emphasizing the study on this type of cereal, aiming at promoting the Public Health.

Loratidine 5 mg also exhibited positive response for Pb, Cd and Ni. Calcium supplements either contained mineral calcium from non-food sources as oyster shell which often described as refined and natural sources or chelated calcium calcium lactate or calcium gluconate.

Six products of calcium supplements were studied; three were exported from USA, one from Switzerland, one from India and the other one from Czech Republic Table 7. There were no local products available to compare with the exported one. All the calcium supplements contained vitamin D except product of Switzerland which contained vitamin C.

However, all the products exhibited higher level of Pb than Cd and Ni. In case of Pb, the recorded level was in the ranges of 0. Amongst the three USA products, one of the products showed higher level 1.

In comparison with product of India 1. The recorded label of Cd in calcium supplements were in the ranges of 0. The recorded level of Ni was in the ranges of 0. The recorded level of Pb was 0. The recorded levels of Cd and Ni in these products were in the ranges of 0.Determination of Lead and Cadmium Contents and Microbial Contamination Assessment in Kohl DOI: / arteensevilla.com 36 | Page and mannitol salt agar while the cultures from sabouraud dextrose broth were streaked onto sabouraud dextrose agar.

Dec 31,  · In this research, heavy metal contents such as lead (Pb), cadmium (Cd) and arsenic (As) were determined in black tea samples cultivated in Guilan and Mazandaran Provinces in north of Iran and their tea infusions. The total arsenic, cadmium, and lead contents were lower than the established legislative values, except for total arsenic in one brown rice sample.

This study indicated the need to establish monitoring programs for emphasizing the study on this type of cereal, aiming at promoting the Public Health. Tissues were homogenised and, g of dry weight sample was digested with 5 ml of HNO 3, for lead and cadmium determination, in Teflon vessels in microwave oven (ANTON PAAR closed vessel microwave digestion system, Graz, Austria).

The metal contents in the samples, expressed in µg kg-1 wet weight, varied from to with an average value of for lead and from to with an average value of for cadmium. ISO specifies a flame atomic absorption spectrometric and inductively coupled plasma spectrometric method for the determination of the lead and cadmium contents in hardmetals.

The method is applicable to products having lead and cadmium contents between 0, 1 % (mass fraction) and 0,1 % (mass fraction).
