The iron content in seminal plasma of normal (n19), oligozoospermic (n11), azoospermic (n12), oligoasthenozoospermic (n19), and asthenozoospermic (n17) subjects was estimated by using atomic absorption spectrophotometer. The concentration of iron in normal seminal plasma varied from 265 to 365 mg%. The source of iron in seminal plasma seems to be the adnexal glands and not spermatozoa, as azoospermic semen also contained it. A statistically highly significant difference was seen when normal was compared with azoospermia and with asthenozoospermia. The necessary average wastage of iron through semen is calculated as 2.52 mg/day. This value is highly variable according to the seminal volume and frequency of ejaculation.

AbstractThe current study was designed to determine the concentrations of toxic metals (Ni, Pb and Cr) in feathers of birds collected from four regions of NE Pakistan. Feather samples of birds (House Crow, Common Myna and House Sparrow) were collected from different areas. Atomic absorption spectrophotometer was used to determine the concentration of metals in feathers. Analysis of the data revealed that concentrations of Pb and Cr were significantly different (p < 0.05) among bird species, whereas no difference (p > 0.05) was detected among bird species (house crow, common myna and house sparrow) for Ni. A significant difference was found for the concentration of Pb and Ni in all the four studied regions. Whereas, non-significant difference was found in all the studied regions for the concentrating of Cr. It was revealed that there is significant rising concentration of metals (Pb, Cr) in feathers of birds in Azad Kashmir.

The study analyses the health risk assessment of the concentration of Iron, Lead, Copper, Chromium, and Cadmium heavy metals in vegetables grown near dumpsites of Jimeta and Ngurore areas of Adamawa State, Nigeria. Vegetables mainly Spinach (Spinacia oleracea) and lettuce (Lactuca sativa) were collected in triplicates and analyzed using Atomic Absorption Spectrophotometer Buck 210VGP (AAS). The result revealed that heavy metals detected in spinach at Jimeta dumpsite decreased in the following order: Fe (3.7 mg/kg) > Pb (0.18 mg/kg) > Cu (0.12 mg/kg) > Cr (0.07 mg/kg) > Cd (below limit of detection), compared to the metal concentration in spinach at Ngorure dumpsite with lower concentration of heavy metal which decreased in the order of: Fe (2.5 mg/kg) > Pb (0.16 mg/kg) > Cu (0.14 mg/kg) > Cr (0.02 mg/kg) > Cd (below limit of detection). Other result for Spinach in Jimeta decreased in the order Fe (3.31mg/kg) > Pb (0.2mg/kg) > Cu (0.11mg/kg) > Cr (0.05mg/kg) > Cd (ND) beyond the limit of detection while Lettuce decreased in the order Fe (22.54mg/kg) > Cu (0.31mg/kg) > Pb (0.12mg/kg) > Cr (0.07mg/kg) > Cd (ND) beyond the limit of detection. Fe is the most abundant element in the vegetables with a mean value of 21 mg/kg followed by Pb (0.177 mg/kg). The analyses of paired T-test for vegetables in Ngurore and Jimeta at 0.05 level of significant confirmed that Cu and Cr showed no statistically significant difference in their concentration level while Fe and Pb confirmed that there was statistically significant difference in their concentration level. However, the detection of heavy metals in these vegetables calls for close environmental monitoring and adequate public awareness. This is necessary to discourage further pollution which could lead to high metal concentration and metal poisoning in vegetables and invariably humans that consume them.

Shellfish is one of the sea products that is very popular with the community including the community in Sinjai Regency as a potential coastal and fishery resources that have a fish auction place (TPI). Shellfish are one of the most efficient marine animals to accumulate heavy metals. This is due to the fact that shellfish live in the bottom sedimentary layer of water, move very slowly, and their food comes from detritus in the bottom waters, so the chance of entering heavy metals into the body is very large. Shells can be contaminated by lead (Pb) which enters the body of water through the crystallization of lead in the air with the help of rain water. Lead which accumulates in water and sediments will enter the water and accumulate in the water causing toxic effects on the organisms in it, including some types of shellfish. If humans consume shells that contain heavy metals in high enough quantities will have a negative impact on health. In the human body, heavy metals will combine with active enzymes to become inactive enzymes, so the synthesis of red blood grains (Hb) can be inhibited, consequently it can cause anemia. The purpose of the study was to determine lead content (Pb) in the sample of shellfish. The object of research is blood shells and mangrove shells, analyzed using the Atomic Absorption Spectrophotometer (SSA) method with a total sample of 10. The results obtained by lead (Pb) in blood shells (Anadara granosa) with an average of 0.0439 mg / kg while the mangrove shells (Telescopium telescopium) with an average of 0.0176 mg / kg. Both shellfish samples did not exceed the maximum limit set by the Indonesian National Standard (SNI) of 1.5 mg / kg. Based on the data analysis test p value = 0.011 <0.05 which can be concluded that there is a significant difference between the levels of lead (Pb) in blood shells (Anadara granosa) and mangrove shells (Telescopium telescopium). Keywords: Blood Shells (Anadara granosa), Mangrove Shells (Telescopium telescopium), Lead (Pb),                  Atomic Absorption Spectrophotometer (SSA)

Nuclear magnetic resonance (NMR) spectroscopy was used to quantify citrate, glucose, lactate, glycerophosphorylcholine and choline in seminal plasma from subjects injected with a new male contraceptive RISUG, a copolymer of styrene maleic anhydride dissolved in dimethyl sulphoxide, and in seminal plasma from normal ejaculates. No significant difference in the concentration of citrate was observed between the groups, indicating that the prostate is not affected by the contraceptive. The concentrations of glucose, lactate, glycerophosphorylcholine and choline were significantly lower (P < 0.01) in subjects injected with RISUG compared with controls. In addition, metabolite ratios such as choline:citrate, citrate:lactate, choline:lactate and glycerophosphorylcholine:choline were calculated. Citrate:lactate and glycerophosphorylcholine:choline ratios were significantly lower in RISUG-injected subjects than in controls (P < 0.01), thereby indicating the occurrence of partial obstructive azoospermia. The most important finding of the present study was that the intervention of RISUG in the vas deferens even for a period as long as 8 years is absolutely safe and does not lead to prostatic diseases.

Determination of oxalate-extractable Si and Al is useful in assessing the degree of accumulation of allophane-like materials in Podzolic soils. Three procedures were tested for determining Si: manual spectrophotometry, automated spectrophotometry and atomic absorption. For concentrations of oxalate-extractable Si above 0.5 g kg−1, there was no significant difference among results by the three procedures. For lower concentrations of Si, results by atomic absorption were higher than those by the spectrophotometric procedures. Determination by Si by autoanalyzer is the preferred procedure as it is convenient, sensitive and reliable. Key words: Oxalate Si, Podzolic soil, autoanalyzer
