The present study uses bird eggs of seven wild species as a biomonitoring tool for sunscreens occurrence. Seven UV filters (UV-Fs), including 3 hydroxy-metabolites of oxybenzone (benzophenone 3, BP3) were characterized in unhatched eggs from Doñana Natural Space (Spain). High frequency of detection was observed for all UV-Fs, ranging from 95% to 100%. The oxybenzone metabolite 4-hydroxybenzophenone (4HB) was ubiquitous at concentrations in the range 12.0–3348 ng g–1 dry weight (dw). The parent compound, oxybenzone, was also present in all samples at lower concentrations (16.9–49.3 ng g–1 dw). Due to the three BP3′s metabolites, benzophenone 1 (BP1), 4HB, and 4,4′-dihydroxybenzophenone (4DHB) presence in unhatched eggs, it can be inferred that parent compounds are absorbed into the bird through the upper gut and the OH-derivatives formed are transferred by the mother to the egg before the lying. White stork (Ciconia ciconia) and western marsh harrier (Circus aeruginosus) were the most contaminated species, with mean total UV-Fs concentrations of 834 and 985 ng g–1 dw, respectively. Results evidenced that biomagnification process across the bird species studied cannot be ruled out.

对野生生物的潜在新威胁：来自保护区的禽蛋中存在紫外线过滤剂
本研究使用七个野生物种的鸟卵作为防晒剂的生物监测工具。在来自DoñanaNatural Space（西班牙）的未孵化卵中，鉴定了七个UV过滤器（UV-Fs），包括3个羟苯甲酮的羟基代谢物（二苯甲酮3，BP3）。对于所有UV-F，观察到的检测频率很高，范围从95％到100％。氧苯酮代谢物4-羟基二苯甲酮（4HB）的浓度范围为12.0–3348 ng g –1干重（dw）。所有样品中的母体化合物氧苯甲酮的含量也较低（16.9–49.3 ng g –1dw）。由于未孵化卵中存在三种BP3的代谢产物二苯甲酮1（BP1），4HB和4,4'-二羟基二苯甲酮（4DHB），因此可以推断出母体化合物是通过上消化道和食道吸收到禽类中的。母亲在产蛋前将形成的OH衍生物转移到鸡蛋上。白鹳（Ciconia ciconia）和西部沼泽（Circus aeruginosus）是受污染最严重的物种，平均总UV-Fs浓度分别为834和985 ng g –1 dw。结果证明不能排除整个研究鸟类的生物放大过程。
