“…Clots in the peripheral blood were autoclaved and transported to Hokkaido University (Kita 8, Nishi 5, Kita-ku, Sapporo, Hokkaido, Japan). The blood Pb level (BLL) was measured using the method of Ushine et al [13] and converted to the amount of Pb per deciliter of a clot.…”

“…The symptoms of impact doses are as follows: increased foraging distance from their own population [7], suppression of humoral immunity [8], and increased production of immunoglobulin E (IgE) and cytokines in response to an allergen that causes inflammation [9–12]. Of these impacts, the effect on immunity can lead to mass mortality in the event of highly pathogenic infections in the habitat of Pb-contaminated birds [13]. It is difficult to point out the effects based on impact dose in wildlife, given that no abnormal symptoms are shown [14].…”

The biological effects of lead (Pb) contamination have been reported in various species. There are no restrictions on the use of Pb products, including bullets, in the areas south of Hokkaido, Japan. Local governments have announced the presence of some Pb in the soil sediments of water bodies. Previous studies have confirmed the relationship between blood Pb level (BLL) and immune cells. This study was performed with the aim of clarifying the effect of Pb contamination on immune cells. In total, 170 Black-headed Gulls (Chroicocephalus ridibundus) were captured, including a population in Tokyo Bay between November 2018 and April 2021 and a population in Mikawa Bay between January 2019 and April 2021. Linear regression analysis was performed with the white blood cell count (WBC), proportion of heterophils (Het), proportion of lymphocytes (Lym), ratio of heterophils and lymphocytes (H/L ratio), copy number of CD4 messenger RNA, and copy number of CD8α messenger RNA as the objective variables, and the BLL as the explanatory variable. The group with BLL < 1.0 μg/dL had a significantly lower Het and higher Lym than that with BLL > 3.5 μg/dL (P < 0.05). In addition, the group with BLL < 1.0 μg/dL had a significantly lower H/L ratio than that with BLL > 3.5 μg/dL. CD8α and WBC were higher in the group with the group with BLL range, from 1.0 to 3.5 μg/dL than those in the group with BLL < 1.0 μg/dL. This study suggests that the effect of Pb pollution on the immune cells of Black-headed Gulls is lower than some previous criteria values.

Lead (Pb), an environmental pollutant, has been widely reported to have contaminated mammals, including humans and birds. This study focuses on the effects of Pb pollution on avian influenza virus (AIV) antibody production. A total of 170 black-headed gulls (Chroicocephalus ridibundus) were captured in Tokyo Bay (TBP) from January 2019 to April 2020 and in Mikawa Bay (MBP) from November 2019 to April 2021. The gulls were weighed, subjected to blood sampling, and released with a ring band on their tarsus. The samples were used to measure blood Pb levels (BLL) and AIV-specific antibodies. The BLL were compared using the Wilcoxon two-sample test between the period when black-headed gulls arrived and the wintering period, defined by the number of gulls counted in each area. A significant increase was found in the TBP. A decrease in BLL significantly increased antibody titer during wintering in TBP and MBP. Pb pollution had a negative effect on the production of AIV antibodies. These findings suggest that wild birds that were contaminated by Pb in the environment may facilitate the spread of zoonotic diseases, further increasing the possibility that environmental pollutants may threaten human health.
