Methodology for estimation of average daily dose

CALCULATION OF AVERAGE DAILY DOSE FOR METAL(LOID)S VIA INGESTION AND DERMAL CONTACT (mg·kg−1·day−1)
Average daily dose for ingestion (ADDing) [14] ADDing=C×IRing×EF×EDBW×AT×CF {ADD_{ing}} = \frac{{C \times I{R_{ing}} \times EF \times ED}}{{BW \times AT}} \times CF
Average daily dose for dermal contact (ADDdermal) [14] ADDdermal=C×SA×AF×ABS×EF×EDBW×AT×CF {ADD_{dermal}} = \frac{{C \times SA \times AF \times ABS \times EF \times ED}}{{BW \times AT}} \times CF
C – element concentration in the sediment sample; IRing – ingestion rate; EF – exposure frequency; ED – exposure duration; AF – adherence factor; ABS – dermal absorption factor; SA – surface area; BW – body weight; AT – averaging time; CF – conversion factor

Ecological risk indices

IndexFormulaScaleDescription

Geoaccumulation Index (Igeo) [12] Igeo=log2cn1.5Bn {I_{geo}} = lo{g_2}\left( {\frac{{{c_n}}}{{1.5{{\rm{B}}_n}}}} \right)
  • Cn – concentration of element in the sediment sample (mg·kg−1),

  • Bn – geochemical background value in the Earth’s crust (Cd=0.1; Cr=100; Cu=55; Ni= 20; Pb=15; Zn=70; As=1.8 mg·kg−1) [44]

Igeo ≤ 0Practically uncontaminated
0<Igeo ≤ 1Uncontaminated to moderately contam.
1<Igeo ≤ 2Moderately contaminated
2<Igeo ≤ 3Moderately to Heavily contam.
3<Igeo ≤ 4Heavily contaminated
4<Igeo ≤ 5Heavily to Extremely contaminated
Igeo >5Extremely contaminated

Potential Ecological Risk Factor (ER) [13] ER=TfiCF ER = T_f^i \cdot CF
  • T – toxic response factor of element (Cd=30; Cr=2; Cu, Ni, Pb=5; Zn=1; As=10);

  • CF – Contamination Factor; the ratio between the concentration of the element in sediment and the background value [13, 44]

ER≤40Low risk
40<ER≤80Moderate risk
80<ER≤160Considerable risk
160<ER≤320High risk

Methodology for health risk assessment

NON-CARCINOGENIC RISK ASSESSMENT
Hazard Quotient (HQ) [14, 15] HQij=ADDijRfDij H{Q_{ij}} = \frac{{AD{D_{ij}}}}{{Rf{D_{ij}}}}
Hazard Index (HI) [14, 15]HI=∑HQij
RfD –reference dose of individual element If the HQ or HI value > 1 – non-carcinogenic risk is possible; if the HQ or HI value < 1 – non-carcinogenic risk is not possible [14, 15]
CARCINOGENIC RISK ASSESSMENT
Carcinogenic Risk (CR) [14, 15]CRij = ADDij × SF TCR = ∑CRij
Total Carcinogenic Risk (TCR) [14, 15]
SF – cancer slope factor If the CR or TCR values > 1×10−4 – the carcinogenic risk occurs; if the values are between 1×10−6 and 1×10−4 – the carcinogenic risk is acceptable; if the values are < 1×10−6 – the risk is not carcinogenic [14, 15]
