在西班牙进行环境污染物对猛禽种群压力的最早研究可追溯到20世纪80年代,通过多种角度使用多种前哨猛禽物种。然而,由于没有国家的监测计划,所以研究无论在时间或是空间上都是零星的。对金属的暴露并没有随着时间的推移变化,但存于卵和组织中的铅浓度有所减少。一般来说,在西班牙猛禽样本中检测到的金属浓度通常很低,不足以产生毒副作用。除DDT和DDe,在过去的20年中西班牙猛禽类中大部分以有机氯为基础的杀虫剂已经减少。在几个不同物种的卵中所发现的DDe浓度可以部分地解释在西班牙猛禽能够成功繁殖的原因。

Three-dimensional programmable transport of micro/nano-particles can be straightforwardly achieved by using optical forces arising from intensity and phase gradients of a structured laser beam. Repulsor and tractor beams based on such forces and shaped in the form of a curved trajectory allow for downstream and upstream(against light propagation) transportation of particles along the beams, respectively. By using both types of beams, bidirectional transport has been demonstrated on the example of a circular helix beam just by tuning its phase gradient. Specifically, the transport of a single particle along a loop of the helix has been reported. However, the design and generation of helix-shaped beams is a complex problem that has not been completely addressed, which makes their practical application challenging. Moreover, there is no evidence of simultaneous transport of multiple particles along the helix trajectory, which is a crucial requisite in practice. Here, we address these challenges by introducing a theoretical background for designing helix beams of any axial extension, shape, and phase gradient that takes into account the experimental limitations of the optical system required for their generation. We have found that only certain phase gradients prescribed along the helix beam are possible. Based on these findings, we have experimentally demonstrated, for the first time, helix-shaped repulsor and tractor beams enabling programmable bidirectional optical transport of particles en masse. This is direct evidence of the essential functional robustness of helix beams arising from their self-reconstructing character. These achievements provide new insight into the behavior of helix-shaped beams, and the proven technique makes their implementation easier for optical transport of particles as well as for other light–matter interaction applications. ? 2022 Chinese Laser Press.
