Data on metals (Zn, Al, Sr, and Co) and metalloid (As) concentration levels of ballast water in commercial ships entering Bushehr port, along the Persian Gulf

Abstract

In this article, we determined the concentration levels of metals including Zn, Al, Sr, and Co and metalloid of As of ballast water in commercial ships entering Bushehr port, along the Persian Gulf. Ballast water samples were taken from commercial ships entering Bushehr port from 34 ports around the world during 15 February and 25 August 2016. The concentration levels of metals and metalloid were determined by using a graphite furnace absorption spectrometer (AAS).

Value of the data

• •Data can be used as a base-line data for metals and metalloid contents in ballast water of commercial ships.
• •Data shown here may motivate further studies on evaluate risk associated with ballast water discharge.
• •Data show that ballast waters discharged by ship tankers in harbors are the main source of metal contamination for sea waters and coral reef in the discharge areas.
• •Data confirmed stricter inspection and supervision as well as permanent monitory program (with respect to ballast water treatment) are necessary for management of ballast water in harbors.

1. Data

In the data, as shown in Table 1, the concentration levels of Zn, Al and Co of ballast water in commercial ships ranged from 1.23 to 6.58, 0.74 to 3.8 and 1.49 to 12.3 ppb respectively. The concentration levels of Sr was not detected (ND) in all examined samples. The concentration levels of As ranged from 0.11 to 1.84 ppb. The highest Zn concentration level was 6.58 ppb in sample S₆ (Kuwait - Kuwait), whereas the lowest Zn concentration level was 1.23 ppb in sample S₁₇ (Muscat- Oman). The highest and lowest concentration levels of Al were 3.8 and 0.74 ppb in samples S₃₄ (Nagoya - Japan) and S₁₁ (Kandla port - India) respectively. The highest and lowest content levels of Co were 12.3 and 1.49 ppb in samples S₂₂ (Navlakhi - India) and S₂₆ (Salalah - Oman) respectively. Finally, the highest concentration level of As was 1.84 ppb in sample S₂₂ (Navlakhi - India) and the lowest level was 0.11 ppb in sample S₁₂ (Ajman port - Emirate).

2. Experimental design, materials and methods

Ballast water samples were taken from commercial ships entering Bushehr port along the Persian Gulf during 15 February and 25 August 2016. Samples were from 34 different ports (see Fig. 1). Each sample was deposited in a 100 ml sterile container, placed in a cooler at −4 °C, and transported to the laboratory at the same day that they were obtained from ship tanker. Samples acidified with nitric acid, and kept for analysis. The concentrations levels of metals and metalloid were determined by using a graphite furnace absorption spectrometer (AAS) method [1] (Varian, SpectrAA 240, Australia).
