“ Samples of urine collected from humans pose a real health risk to laboratory workers who collect and handle these samples. These risks are primarily due to personal contact with infective biological samples and can have serious health consequences, such as infectious hepatitis, and other diseases. ”

“ Agitate samples (on the shaker) for at least 12 h. Filter samples through a 0.8-μm cellulose ester membrane filter, saving the filtrate and resin. Place the collected resin and filter in a clean 50-mL beaker. Adjust filtrate pH to 8.0 ± 0.1 with 5 M NaOH, add more resin, then repeat steps 5 and 6, combining the filters and resins from the two extractions. Ash filters and resins in a low temperature oxygen plasma asher for 6 h or until ashing is NIOSH Manual of Analytical Methods (NMAM) , Fourth Edition, 8/15/94 METALS in urine: METHOD 8310, Issue 2, dated 15 August 1994 - Page 3 of 5 10. 11. ”

“ This method measures urine concentrations of metals. It is particularly useful for workers exposed to several metals simultaneously. This is a simultaneous, multielemental analysis, but is not compound specific. INTERFERENCES: Spectral interferences are the primary interferences encountered in ICP-AES analysis. These are minimized by judicious wavelength selection and interelement correction factors. Background corrections are also made [1,2] . OTHER METHODS: This method uses a measurement technique similar to that of Method 7300 (Elements by ICP) for air samples. ”
