An Investigation for Heavy Metals’ Contamination in Farmers’ Fingernails: Case Study in Libya

Table 2

Linear range, correlation coefficient, and limits of detection (LOD) and limits of quantification (LOQ) values for calculating As, Cd, and Pb using ICP-MS.

Heavy metals	Linear range (µgL^−1)	Correlation coefficient (r)	LOD (µgg^−1)	LOQ (µgg^−1)	Recovery (%)	Relative accuracy error (%)
As	10 to 100	0.9995	0.0077	0.0258	98.3	1.22
Cd	10 to 100	0.9997	0.0019	0.0063	97.9	2.42
Pb	10 to 100	0.9998	0.0012	0.0038	92.3	3.28
