This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels in the field. This kit is also compatable with testing for Lead in Soil. Please inquire for sample extration and testing methods – sales@attogene.com
This is a revolutionary product designed to make Lead testing in water safe, easy, and affordable. This fast screening test kit contains 10 tests with everything needed for accurate results of unsafe lead levels. With reliable results in only 10 minutes, this test kit clearly gives results confirming Lead in water and conforming to the EPA guideline of 15 ppb (g/L). The kit can test water quality from various sources including faucets, wells (ground water), and home purification systems.
Standards and Regulations for Lead [ACCLPP 2012]
- EPA: Drinking Water: 15ppb
- FDA: Juice: 50ppb
- EPA: Residential Soil: 400 ppm (play areas), 1200 ppm (non-play areas)
- CPSC: Paint: 90ppm
- FDA: Bottled drinking water: 5ppb
High Blood lead levels (i.e., greater than 700ppb) can cause serious health effects, including seizure, coma, and death. Blood levels as low as 100ppb have been associated with adverse effects on cognitive development, growth, and behavior among children aged 1-5 years.
Sample method:
1. Take a first-draw sample
Immediately after opening a faucet or valve, collect a 250 mL sample.This sample should be from each tap used for consumption.
2. Take a flush sample
If first-draw sample results show elevated lead levels of 5 ppb or higher, collect a flush sample.To do this, ensure water has not been used for between 8 to 18 hours, then collect the sample at 30 seconds.
3. Take sequential samples
If you want to test a lead service line, collect 8 to 10 sequential samples, depending on how far the line is from the tap.
LEAD in SOIL:
Recognizing the role of soil as a potentially important source of Pb exposure of children in particular, the US EPA recently lowered the recommended residential screening level from 400 to 200 mg/kg total Pb in soil The adjustment was overdue given that the blood- Pb concentration of a child above which the Centers for Disease Control and Prevention (CDC) recommends a home inspection had been lowered from 10 to 5 μg/dL in 2012 and further down to 3.5 μg/dL in 2021. One of the assumptions underlying the screening level is that 30 % of the total soil Pb is bioavailable (US EPA, 2007). For reference, a soluble form such as Pb acetate is assumed to be about 50% bioavailable. The actual bioavailability of soil Pb in the environment estimated by in vitro assays
ranges widely depending on the setting.
